This is similar to the existing CA constraints but doesn't require that the CA certificate is locally installed, for instance, intermediate CA certificates received from the peers. Wildcard identity matching (e.g. ..., OU=Research, CN=*) could also be used for the latter but requires trust in the intermediate CAs to only issue certificates with legitimate subject DNs (e.g. the "Sales" CA must not issue certificates with OU=Research). With the new constraint that's not necessary as long as a path length basic constraint (--pathlen for pki --issue) prevents intermediate CAs from issuing further intermediate CAs. * Intermediate CA certificates may now be sent in hash-and-URL encoding by configuring a base URL for the parent CA (#3234, swanctl/rw-hash-and-url-multi-level). * Implemented NIST SP-800-90A Deterministic Random Bit Generator (DRBG) based on AES-CTR and SHA2-HMAC modes. Currently used by the gmp and ntru plugins. * Random nonces sent in an OCSP requests are now expected in the corresponding OCSP responses. * The kernel-netlink plugin now ignores deprecated IPv6 addresses for MOBIKE. Whether temporary or permanent IPv6 addresses are included now depends on the charon.prefer_temporary_addrs setting (#3192). * Extended Sequence Numbers (ESN) are configured via PF_KEY if supported by the kernel. * The PF_KEY socket's receive buffer in the kernel-pfkey plugin is now cleared before sending requests, as many of the messages sent by the kernel are sent as broadcasts to all PF_KEY sockets. This is an issue if an external tool is used to manage SAs/policies unrelated to IPsec (#3225). * The vici plugin now uses unique section names for CHILD_SAs in child-updown events (7c74ce9190). * For individually deleted CHILD_SAs (in particular for IKEv1) the vici child-updown event now includes more information about the CHILD_SAs such as traffic statistics (#3198). * Custom loggers are correctly re-registered if log levels are changed via stroke loglevel (#3182). * Avoid lockups during startup on low entropy systems when using OpenSSL 1.1.1 (095a2c2eac). * Instead of failing later when setting a key, creating HMACs via openssl plugin now fails instantly if the underlying hash algorithm isn't supported (e.g. MD5 in FIPS-mode) so fallbacks to other plugins work properly (#3284). * Exponents of RSA keys read from TPM 2.0 via SAPI are correctly converted (8ee1242f1438). * Routing table IDs > 255 are supported for custom routes on Linux. * To avoid races, the check for hardware offloading support in the kernel-netlink plugin is performed during initialization of the plugin (a605452c03). * The D-Bus config file for charon-nm is now installed in $(datadir)/dbus-1/system.d instead of $(sysconfdir)/dbus-1/system.d, which is intended for sysadmin overrides. INVALID_MAJOR_VERSION notifies are now correctly sent in messages of the same exchange type and with the same message ID as the request. * IKEv2 SAs are now immediately destroyed when sending or receiving INVALID_SYNTAX notifies in authenticated messages. * For developers working from the repository the configure script now aborts if GNU gperf is not found. - Version 5.8.1 =============== * RDNs in DNs of X.509 certificates can now optionally be matched less strict. The global strongswan.conf option charon.rdn_matching takes two alternative values that cause the matching algorithm to either ignore the order of matched RDNs (reordered) or additionally (relaxed) accept DNs that contain more RDNs than configured (unmatched RDNs are treated like wildcard matches). * The updown plugin now passes the same interface to the script that is also used for the automatically installed routes, that is, the interface over which the peer is reached instead of the interface on which the local address is found (#3095). * TPM 2.0 contexts are now protected by a mutex to prevent issues if multiple IKE_SAs use the same private key concurrently (4b25885025). * Do a rekey check after the third QM message was received (#3060). * If available, explicit_bzero() is now used as memwipe() instead of our own implementation. * An .editorconfig file has been added, mainly so Github shows files with proper indentation (68346b6962). * The internal certificate of the load-tester plugin has been modified so it can again be used as end-entity cert with 5.6.3 and later (#3139). * The maximum data length of received COOKIE notifies (64 bytes) is now enforced (#3160). - Version 5.8.0 =============== * The systemd service units have been renamed. The modern unit, which was called strongswan-swanctl, is now called strongswan (the previous name is configured as alias in the unit, for which a symlink is created when the unit is enabled). The legacy unit is now called strongswan-starter. * Support for XFRM interfaces (available since Linux 4.19) has been added, which are intended to replace VTI devices (they are similar but offer several advantages, for instance, they are not bound to an address or address family). * IPsec SAs and policies are associated with such interfaces via interface IDs that can be configured in swanctl.conf (dynamic IDs may optionally be allocated for each SA and even direction). It's possible to use separate interfaces for in- and outbound traffic (or only use an interface in one direction and regular policies in the other). * Interfaces may be created dynamically via updown/vici scripts, or statically before or after establishing the SAs. Routes must be added manually as needed (the daemon will not install any routes for outbound policies with an interface ID). * When moving XFRM interfaces to other network namespaces they retain access to the SAs and policies installed in the original namespace, which allows providing IPsec tunnels for processes in other network namespaces without giving them access to the IPsec keys or IKE credentials. More information can be found on the page about route-based VPNs. * Initiation of childless IKE_SAs is supported (RFC 6023). If enabled and supported by the responder, no CHILD_SA is established during IKE_AUTH. Instead, all CHILD_SAs are created with CREATE_CHILD_SA exchanges. This allows using a separate DH exchange even for the first CHILD_SA, which is otherwise created during IKE_AUTH with keys derived from the IKE_SA's key material. * The swanctl --initiate command may be used to initiate only the IKE_SA via --ike option if --child is omitted and the peer supports this extension. * The NetworkManager backend and plugin support IPv6. * The new wolfssl plugin is a wrapper around the wolfSSL crypto library. Thanks to Sean Parkinson of wolfSSL Inc. for the initial patch. * IKE SPIs may optionally be labeled via the charon.spi_mask|label options in strongswan.conf. This feature was extracted from charon-tkm, however, now applies the mask/label in network order. * The openssl plugin supports ChaCha20-Poly1305 when built with OpenSSL 1.1.0. * The PB-TNC finite state machine according to section 3.2 of RFC 5793 was not correctly implemented when sending either a CRETRY or SRETRY batch. These batches can only be sent in the "Decided" state and a CRETRY batch can immediately carry all messages usually transported by a CDATA batch. It is currently not possible to send a SRETRY batch since full-duplex mode for PT-TLS transport is not supported. * Instead of marking IPv6 virtual IPs as deprecated, the kernel-netlink plugin now uses address labels to avoid that such addresses are used for non-VPN traffic (00a953d090). * The agent plugin now creates sockets to the ssh/gpg-agent dynamically and does not keep them open, which otherwise might prevent the agent from getting terminated. * To avoid broadcast loops the forecast plugin now only reinjects packets that are marked or received from the configured interface. * UTF-8 encoded passwords are supported via EAP-MSCHAPv2, which internally uses an UTF-16LE encoding to calculate the NT hash (#3014). * Properly delete temporary drop policies (used when updating IP addresses of SAs) if manual priorities are used, which was broken since 5.6.2 (8e31d65730). * Avoid overwriting start_action when parsing the inactivity timeout in the vici plugin (#2954). * Fixed the automatic termination of reloaded vici connections with start_action=start, which was broken since 5.6.3 (71b22c250f). * The lookup for shared secrets for IKEv1 SAs via sql plugin should now work better (6ec9f68f32). * Fixed a race condition in the trap manager between installation and removal of a policy (69cbe2ca3f). * Compilation of the kernel-netlink plugin has been fixed on old kernels (< 2.6.39), which was caused by the HW offload changes (c7f579fa17). * The IPsec stack detection and module loading in starter has been removed (it wasn't enforced anyway and loading modules doesn't seem necessary, also KLIPS hasn't been supported for a long time and PF_KEY will eventually be removed from the Linux kernel, ba817d2917). * Several IKEv2 protocol details are now handled more strictly: Unrequested virtual IPs are ignored, CFG_REPLY payloads are ignored if no CFG_REQUEST payloads were sent, a USE TRANSPORT_MODE notify received from the responder is checked against the local configuration. * The keys and certificates used by the scenarios in the testing environment are now generated dynamically. Running the testing/scripts/build-certs script after creating the base and root images uses the pki utility installed in the latter to create the keys and certificates for all the CAs and in some cases for individual scenarios. These credentials are stored in the source tree, not the image, so this has to be called only once even if the images are later rebuilt. The script automatically (re-)rebuilds the guest images as that generates fresh CRLs and signs the DNS zones. The only keys/certificates currently not generated are the very large ones used by the ikev2/rw-eap-tls-fragments scenario. - Version 5.7.2 =============== * For RSA with PSS padding, the TPM 2.0 specification mandates the maximum salt length (as defined by the length of the key and hash). However, if the TPM is FIPS-168-4 compliant, the salt length equals the hash length. This is assumed for FIPS-140-2 compliant TPMs, but if that's not the case, it might be necessary to manually enable charon.plugins.tpm.fips_186_4 if the TPM doesn't use the maximum salt length. * Directories for credentials loaded by swanctl are now accessed relative to the loaded swanctl.conf file, in particular, when loading it from a custom location via --file argument. * The base directory, which is used if no custom location for swanctl.conf is specified, is now also configurable at runtime via SWANCTL_DIR environment variable. * If RADIUS Accounting is enabled, the eap-radius plugin will add the session ID (Acct-Session-Id) to Access-Request messages, which e.g. simplifies associating database entries for IP leases and accounting with sessions (the session ID does not change when IKE_SAs are rekeyed, #2853). * All IP addresses assigned by a RADIUS server are included in Accounting-Stop messages even if the client did not claim them, allowing to release them early in case of connection errors (#2856). * Selectors installed on transport mode SAs by the kernel-netlink plugin are now updated if an IP address changes (e.g. via MOBIKE) and it was part of the selectors. * No deletes are sent anymore when a rekeyed CHILD_SA expires (#2815). * The bypass-lan plugin now tracks interfaces to handle subnets that move from one interface to another and properly update associated routes (#2820). * Only valid and expected inbound IKEv2 messages are used to update the timestamp of the last received message (previously, retransmits also triggered an update). * IKEv2 requests from responders are now ignored until the IKE_SA is fully established (e.g. if a DPD request from the peer arrives before the IKE_AUTH response does, 46bea1add9). Delayed IKE_SA_INIT responses with COOKIE notifies we already recevied are ignored, they caused another reset of the IKE_SA previously (#2837). * Active and queued Quick Mode tasks are now adopted if the peer reauthenticates an IKEv1 SA while creating lots of CHILD_SAs. * Newer versions of the FreeBSD kernel add an SADB_X_EXT_SA2 extension to SADB_ACQUIRE messages, which allows the kernel-pfkey plugin to determine the reqid of the policy even if it wasn't installed by the daemon previously (e.g. when using FreeBSD's if_ipsec(4) VTIs, which install policies themselves, 872b9b3e8d). * Added support for RSA signatures with SHA-256 and SHA-512 to the agent plugin. For older versions of ssh/gpg-agent that only support SHA-1, IKEv2 signature authentication has to be disabled via charon.signature_authentication. * The sshkey and agent plugins support Ed25519/Ed448 SSH keys and signatures. * The openssl plugin supports X25519/X448 Diffie-Hellman and Ed25519/Ed448 keys and signatures when built against OpenSSL 1.1.1. * Support for Ed25519, ChaCha20/Poly1305, SHA-3 and AES-CCM were added to the botan plugin. * The mysql plugin now properly handles database connections with transactions under heavy load (#2779). * IP addresses in ha pools are now distributed evenly among all segments (#2828). * Private key implementations may optionally provide a list of supported signature schemes, which, as described above, is used by the tpm plugin because for each key on a TPM 2.0 the hash algorithm and for RSA also the padding scheme is predefined. * The testing environment is now based on Debian 9 (stretch) by default. This required some changes, in particular, updating to FreeRADIUS 3.x (which forced us to abandon the TNC@FHH patches and scenarios, 2fbe44bef3) and removing FIPS-enabled versions of OpenSSL (the FIPS module only supports OpenSSL 1.0.2). * Most test scenarios were migrated to swanctl. - Version 5.7.1 =============== * Fixes a vulnerability in the gmp plugin triggered by crafted certificates with RSA keys with very small moduli. When verifying signatures with such keys, the code patched with the fix for CVE-2018-16151/2 caused an integer underflow and subsequent heap buffer overflow that results in a crash of the daemon. * The vulnerability has been registered as CVE-2018-17540. - Version 5.7.0 =============== * Fixes a potential authorization bypass vulnerability in the gmp plugin that was caused by a too lenient verification of PKCS#1 v1.5 signatures. Several flaws could be exploited by a Bleichenbacher-style attack to forge signatures for low-exponent keys (i.e. with e=3). * CVE-2018-16151 has been assigned to the problem of accepting random bytes after the OID of the hash function in such signatures, and CVE-2018-16152 has been assigned to the issue of not verifying that the parameters in the ASN.1 algorithmIdentitifer structure is empty. Other flaws that don't lead to a vulnerability directly (e.g. not checking for at least 8 bytes of padding) have no separate CVE assigned. * Dots are not allowed anymore in section names in swanctl.conf and strongswan.conf. This mainly affects the configuration of file loggers. If the path for such a log file contains dots it now has to be configured in the new path setting within the arbitrarily renamed subsection in the filelog section. * Sections in swanctl.conf and strongswan.conf may now reference other sections. All settings and subsections from such a section are inherited. This allows to simplify configs as redundant information has only to be specified once and may then be included in other sections (see strongswan.conf for an example). * The originally selected IKE config (based on the IPs and IKE version) can now change if no matching algorithm proposal is found. This way the order of the configs doesn't matter that much anymore and it's easily possible to specify separate configs for clients that require weaker algorithms (instead of having to also add them in other configs that might be selected). * Support for Postquantum Preshared Keys for IKEv2 (draft-ietf-ipsecme-qr-ikev2) has been added. For an example refer to the swanctl/rw-cert-ppk scenario (or with EAP, or PSK authentication). * The new botan plugin is a wrapper around the Botan C++ crypto library. It requires a fairly recent build from Botan's master branch (or the upcoming 2.8.0 release). Thanks to René Korthaus and his team from Rohde & Schwarz Cybersecurity for the initial patch and to Jack Lloyd for quickly adding missing functions to Botan's FFI (C89) interface. * Implementation of RFC 8412 "Software Inventory Message and Attributes (SWIMA) for PA-TNC". * SWIMA subscription option sets CLOSE_WRITE trigger on apt history.log file resulting in a ClientRetry PB-TNC batch to initialize a new measurement cycle. The new imv/imc-swima plugins replace the previous imv/imc-swid plugins, which were removed. * Added support for fuzzing the PA-TNC (RFC 5792) and PB-TNC (RFC 5793) NEA protocols on Google's OSS-Fuzz infrastructure. * Support for version 2 of Intel's TPM2-TSS TGC Software Stack. The presence of the in-kernel /dev/tpmrm0 resource manager is automatically detected. * The pki tool accepts a xmppAddr otherName as a subjectAlternativeName using the syntax --san xmppaddr:<jid>. * swanctl.conf supports the configuration of marks the in- and/or outbound SA should apply to packets after processing on Linux. Configuring such a mark for outbound SAs requires at least a 4.14 kernel. The ability to set a mask and configuring a mark/mask for inbound SAs will be added with the upcoming 4.19 kernel. * New options in swanctl.conf allow configuring how/whether DF, ECN and DS fields in the IP headers are copied during IPsec processing. Controlling this is currently only possible on Linux. * The handling of sequence numbers in IKEv1 DPDs has been improved (#2714). * To avoid conflicts, the dhcp plugin now only uses the DHCP server port if explicitly configured. - Version 5.6.3 =============== * Fixed a DoS vulnerability in the IKEv2 key derivation if the openssl plugin is used in FIPS mode and HMAC-MD5 is negotiated as PRF. This vulnerability has been registered as CVE-2018-10811. * Fixed a vulnerability in the stroke plugin, which did not check the received length before reading a message from the socket. Unless a group is configured, root privileges are required to access that socket, so in the default configuration this shouldn't be an issue. This vulnerability has been registered as CVE-2018-5388. * CRLs that are not yet valid are now ignored to avoid problems in scenarios where expired certificates are removed from new CRLs and the clock on the host doing the revocation check is trailing behind that of the host issuing CRLs. Not doing this could result in accepting a revoked and expired certificate, if it's still valid according to the trailing clock but not contained anymore in not yet valid CRLs. * The issuer of fetched CRLs is now compared to the issuer of the checked certificate (#2608). * CRL validation results other than revocation (e.g. a skipped check because the CRL couldn't be fetched) are now stored also for intermediate CA certificates and not only for end-entity certificates, so a strict CRL policy can be enforced in such cases. * In compliance with RFC 4945, section 5.1.3.2, certificates used for IKE must now either not contain a keyUsage extension (like the ones generated by pki), or have at least one of the digitalSignature or nonRepudiation bits set. * New options for vici/swanctl allow forcing the local termination of an IKE_SA. This might be useful in situations where it's known the other end is not reachable anymore, or that it already removed the IKE_SA, so retransmitting a DELETE and waiting for a response would be pointless. * Waiting only a certain amount of time for a response (i.e. shorter than all retransmits would be) before destroying the IKE_SA is also possible by additionally specifying a timeout in the forced termination request. * When removing routes, the kernel-netlink plugin now checks if it tracks other routes for the same destination and replaces the installed route instead of just removing it. Same during installation, where existing routes previously weren't replaced. This should allow using traps with virtual IPs on Linux (#2162). * The dhcp plugin now only sends the client identifier DHCP option if the identity_lease setting is enabled (7b660944b6). It can also send identities of up to 255 bytes length, instead of the previous 64 bytes (30e886fe3b, 0e5b94d038). If a server address is configured, DHCP requests are now sent from port 67 instead of 68 to avoid ICMP port unreachables (becf027cd9). * The handling of faulty INVALID_KE_PAYLOAD notifies (e.g. one containing a DH group that wasn't proposed) during CREATE_CHILD_SA exchanges has been improved (#2536). * Roam events are now completely ignored for IKEv1 SAs (there is no MOBIKE to handle such changes properly). * ChaCha20/Poly1305 is now correctly proposed without key length (#2614). For compatibility with older releases the chacha20poly1305compat keyword may be included in proposals to also propose the algorithm with a key length (c58434aeff). * Configuration of hardware offload of IPsec SAs is now more flexible and allows a new setting (auto), which automatically uses it if the kernel and device both support it. If hw offload is set to yes and offloading is not supported, the CHILD_SA installation now fails. * The kernel-pfkey plugin optionally installs routes via internal interface (one with an IP in the local traffic selector). On FreeBSD, enabling this selects the correct source IP when sending packets from the gateway itself (e811659323). * SHA-2 based PRFs are supported in PKCS#8 files as generated by OpenSSL 1.1 (#2574). * The pki --verify tool may load CA certificates and CRLs from directories. * The IKE daemon now also switches to port 4500 if the remote port is not 500 (e.g. because the remote maps the response to a different port, as might happen on Azure), as long as the local port is 500 (85bfab621d). * Fixed an issue with DNS servers passed to NetworkManager in charon-nm (ee8c25516a). * Logged traffic selectors now always contain the protocol if either protocol or port are set (a36d8097ed). * Only the inbound SA/policy will be updated as reaction to IP address changes for rekeyed CHILD_SAs that are kept around. * The parser for strongswan.conf/swanctl.conf now accepts = characters in values without having to put the value in quotes (e.g. for Base64 encoded shared secrets). Notes for developers: * trap_manager_t: Trap policies are now unistalled by peer/child name and not the reqid. * No reqid is returned anymore when installing trap policies. * child_sa_t: A new state (CHILD_DELETED) is used for CHILD_SAs that have been deleted but not yet destroyed (after a rekeying CHILD_SAs are kept around for a while to process delayed packets). This way child_updown events are not triggered anymore for such SAs when an IKE_SA that has such CHILD_SAs assigned is deleted. - Version 5.6.2 =============== * Fixed a DoS vulnerability in the parser for PKCS#1 RSASSA-PSS signatures that was caused by insufficient input validation. One of the configurable parameters in algorithm identifier structures for RSASSA-PSS signatures is the mask generation function (MGF). Only MGF1 is currently specified for this purpose. However, this in turn takes itself a parameter that specifies the underlying hash function. strongSwan's parser did not correctly handle the case of this parameter being absent, causing an undefined data read. This vulnerability has been registered as CVE-2018-6459. * When rekeying IKEv2 IKE_SAs the previously negotiated DH group will be reused, instead of using the first configured group, which avoids an additional exchange if the peer previously selected a different DH group via INVALID_KE_PAYLOAD notify. The same is also done when rekeying CHILD_SAs except for the first rekeying of the CHILD_SA that was created with the IKE_SA, where no DH group was negotiated yet. Also, the selected DH group is moved to the front in all sent proposals that contain it and all proposals that don't are moved to the back in order to convey the preference for this group to the peer. * Handling of MOBIKE task queuing has been improved. In particular, the response to an address update (with NAT-D payloads) is not ignored anymore if only an address list update or DPD is queued as that could prevent updating the UDP encapsulation in the kernel. * On Linux, roam events may optionally be triggered by changes to the routing rules, which can be useful if routing rules (instead of e.g. route metrics) are used to switch from one to another interface (i.e. from one to another routing table). Since routing rules are currently not evaluated when doing route lookups this is only useful if the kernel-based route lookup is used (4664992f7d). * The fallback drop policies installed to avoid traffic leaks when replacing addresses in installed policies are now replaced by temporary drop policies, which also prevent acquires because we currently delete and reinstall IPsec SAs to update their addresses (35ef1b032d). * Access X.509 certificates held in non-volatile storage of a TPM 2.0 referenced via the NV index. Adding the --keyid parameter to pki --print allows to print private keys or certificates stored in a smartcard or a TPM 2.0. * Fixed proposal selection if a peer incorrectly sends DH groups in the ESP proposal during IKE_AUTH and also if a DH group is configured in the local ESP proposal and charon.prefer configured_proposals is disabled (d058fd3c32). * The lookup for PSK secrets for IKEv1 has been improved for certain scenarios (see #2497 for details). * MSKs received via RADIUS are now padded to 64 bytes to avoid compatibility issues with EAP-MSCHAPv2 and PRFs that have a block size < 64 bytes (e.g. AES-XCBC-PRF-128, see 73cbce6013). * The tpm_extendpcr command line tool extends a digest into a TPM PCR. * Ported the NetworkManager backend from the deprecated libnm-glib to libnm. * The save-keys debugging/development plugin saves IKE and/or ESP keys to files compatible with Wireshark. - Version 5.6.1 =============== * Several algorithms were removed from the default ESP/AH and IKE proposals in compliance with RFC 8221 and RFC 8247, respectively. Removed from the default ESP/AH proposal were the 3DES and Blowfish encryption algorithms and the HMAC-MD5 integrity algorithm. From the IKE default proposal the HMAC-MD5 integrity algorithm and the MODP-1024 Diffie-Hellman group were removed (the latter is significant for Windows clients in their default configuration). These algorithms may still be used in custom proposals. * Support for RSASSA-PSS signatures has been added. For compatibility with previous releases they are currently not used automatically, by default, to change that charon.rsa_pss may be enabled. To explicitly use or require such signatures during IKEv2 signature authentication (RFC 7427) ike:rsa/pss... authentication constraints may be used for specific connections (regardless of whether the strongswan.conf option above is enabled). Only the hash algorithm can be specified in such constraints, the MGF1 will be based on that hash and the salt length will equal the hash length (when verifying the salt length is not enforced). To enforce such signatures during PKI verification use rsa/pss... authentication constraints. * All pki commands that create certificates/CRLs can be made to sign with RSASSA-PSS instead of the classing PKCS#1 scheme with the --rsa-padding pss option. As with signatures during authentication, only the hash algorithm is configurable (via --digest option), the MGF1 will be based on that and the salt length will equal the hash length. * These signatures are supported by all RSA backends except pkcs11 (i.e. gmp, gcrypt, openssl). The gmp plugin requires the mgf1 plugin. Note that RSASSA-PSS algorithm identifiers and parameters in keys (public keys in certificates or private keys in PKCS#8 files) are currently not used as constraints. * The sec-updater tool checks for security updates in dpkg-based repositories (e.g. Debian/Ubuntu) and sets the security flags in the IMV policy database accordingly. Additionally for each new package version a SWID tag for the given OS and HW architecture is created and stored in the database. * Using the sec-updater.sh script template the lookup can be automated (e.g. via an hourly cron job). * When restarting an IKEv2 negotiation after receiving an INVALID_KE_PAYLOAD notify (or due to other reasons like too many retransmits) a new initiator SPI is allocated. This prevents issues caused by retransmits for IKE_SA_INIT messages. * Because the initiator SPI was previously reused when restarting the connection delayed responses for previous connection attempts were processed and might have caused fatal errors due to a failed DH negotiation or because of the internal retry counter in the ike-init task. For instance, if we proposed a DH group the responder rejected we might have later received delayed responses that either contained INVALID_KE_PAYLOAD notifies with the DH group we already switched to, or, if we retransmitted an IKE_SA_INIT with the requested group but then had to restart again, a KE payload with a group different from the one we proposed. * The introduction of file versions in the IMV database scheme broke file reference hash measurements. This has been fixed by creating generic product versions having an empty package name. * A new timeout option for the systime-fix plugin stops periodic system time checks after a while and enforces a certificate verification, closing or reauthenticating all SAs with invalid certificates. * The IKE event counters, previously only available via ipsec listcounters command, may now also be queried and reset via vici and the new swanctl --counters command. They are collected and provided by the optional counters plugin (enabled by default for backwards compatibility if the stroke plugin is built). * Class attributes received in RADIUS Access-Accept messages may optionally be added to RADIUS accounting messages (655924074b). * Basic support for systemd sockets has been added, which may be used for privilege separation (59db98fb94). * Inbound marks may optionally be installed in the SA again (was removed with 5.5.2) by enabling the mark_in_sa option in swanctl.conf. * The timeout of leases in pools configured via pool utility may be configured in other units than hours. INITIAL_CONTACT notifies are now only omitted if never is configured as uniqueness policy. * Outbound FWD policies for shunts are not installed anymore, by default (as is the case for other policies since 5.5.1). * Don't consider a DH group mismatch during CHILD_SA rekeying as failure as responder (e7276f78aa). * Handling of fragmented IPv4 and IPv6 packets in libipsec has been improved (e138003de9). * Trigger expire events for the correct IPsec SA in libipsec (6e861947a0). * A crash in CRL verification via openssl plugin using OpenSSL 1.1 has been fixed (78acaba6a1). * No hard-coded default proposals are passed from starter to the stroke plugin anymore (the IKE proposal used curve25519 since 5.5.2, which is an optional plugin). * A workaround for an issue with virtual IPs on macOS 10.13 (High Sierra) has been added (039b85dd43). * Handling of IKE_SA rekey collisions in charon-tkm has been fixed. * Instead of failing or just silently doing nothing unit tests may now warn about certain conditions (e.g. if a test was not executed due to external dependencies). ------------------------------------------------------------------- Thu Nov 14 12:56:01 UTC 2019 - Madhu Mohan Nelemane <mmnelemane@suse.com> - Added patch to fix vulnerability: CVE-2018-17540 (bsc#1109845) [+ 0010-strongswan-4.4.0-5.7.0_gmp-pkcs1-overflow.patch] ------------------------------------------------------------------- Wed Nov 13 16:43:52 UTC 2019 - Madhu Mohan Nelemane <mmnelemane@suse.com> - Added patch to fix vulnerability: CVE-2018-10811 (bsc#1093536) - denial-of-service vulnerability [+ 0009-strongswan-5.5.0-5.6.2_skeyseed_init.patch] ------------------------------------------------------------------- Wed Nov 13 15:41:29 UTC 2019 - Madhu Mohan Nelemane <mmnelemane@suse.com> - Added patch to fix vulnerability: CVE-2018-5388 (bsc#1094462) - Buffer Underflow in stroke_socket.c [+ 0008-strongswan-5.1.2-5.6.2_stroke_msg_len.patch] ------------------------------------------------------------------- Wed Nov 13 13:51:38 UTC 2019 - Madhu Mohan Nelemane <mmnelemane@suse.com> - Added patch to fix vulnerability: CVE-2018-16151,CVE-2018-16152 (bsc#1107874) - Insufficient input validation in gmp plugin [+ 0007-strongswan-5.3.1-5.6.0_gmp-pkcs1-verify.patch] ------------------------------------------------------------------- Wed Mar 14 15:43:42 UTC 2018 - mmnelemane@suse.com - Removed unused requires and macro calls(bsc#1083261) ------------------------------------------------------------------- Tue Sep 5 17:10:11 CEST 2017 - ndas@suse.de - Updated to strongSwan 5.6.0 providing the following changes: *Fixed a DoS vulnerability in the gmp plugin that was caused by insufficient input validation when verifying RSA signatures, which requires decryption with the operation m^e mod n, where m is the signature, and e and n are the exponent and modulus of the public key. The value m is an integer between 0 and n-1, however, the gmp plugin did not verify this. So if m equals n the calculation results in 0, in which case mpz_export() returns NULL. This result wasn't handled properly causing a null-pointer dereference. This vulnerability has been registered as CVE-2017-11185. (bsc#1051222) *New SWIMA IMC/IMV pair implements the draft-ietf-sacm-nea-swima-patnc Internet Draft and has been demonstrated at the IETF 99 Prague Hackathon. *The IMV database template has been adapted to achieve full compliance with the ISO 19770-2:2015 SWID tag standard. *The pt-tls-client can attach and use TPM 2.0 protected private keys via the --keyid parameter. *By default the /etc/swanctl/conf.d directory is created and *.conf files in it are included in the default swanctl.conf file. *The curl plugin now follows HTTP redirects (configurable via strongswan.conf). *The CHILD_SA rekeying was fixed in charon-tkm and the behavior is refined a bit more since 5.5.3 *libtpmtss supports Intel's TSS2 Architecture Broker and Resource Manager interface (tcti-tabrmd). * more on https://wiki.strongswan.org/versions/66 ------------------------------------------------------------------- Tue Sep 5 11:33:01 CEST 2017 - ndas@suse.de - fix "uintptr_t’ undeclared" compilation error.

More specifically, mpz_powm_sec() has two requirements regarding the passed exponent and modulus that the plugin did not enforce, if these are not met the calculation will result in a floating point exception that crashes the whole process. This vulnerability has been registered as CVE-2017-9022. Please refer to our blog for details. *Fixed a DoS vulnerability in the x509 plugin that was caused because the ASN.1 parser didn't handle ASN.1 CHOICE types properly, which could result in an infinite loop when parsing X.509 extensions that use such types. This vulnerability has been registered as CVE-2017-9023. Please refer to our blog for details. *The behavior during IKEv2 CHILD_SA rekeying has been changed in order to avoid traffic loss. When responding to a CREATE_CHILD_SA request to rekey a CHILD_SA the responder already has everything available to install and use the new CHILD_SA. However, this could lead to lost traffic as the initiator won't be able to process inbound packets until it processed the CREATE_CHILD_SA response and updated the inbound SA. To avoid this the responder now only installs the new inbound SA and delays installing the outbound SA until it receives the DELETE for the replaced CHILD_SA. *The messages transporting these DELETEs could reach the peer before packets sent with the deleted outbound SAs reach it. To reduce the chance of traffic loss due to this the inbound SA of the replaced CHILD_SA is not removed for a configurable amount of seconds (charon.delete_rekeyed_delay) after the DELETE has been processed. *The code base has been ported to Apple's ARM64 iOS platform, which required several changes regarding the use of variadic functions. This was necessary because the calling conventions for variadic and regular functions are different there. This means that assigning a non-variadic function to a variadic function pointer, as we did with our enumerator_t::enumerate() implementations and several callbacks, will result in crashes as the called function accesses the arguments differently than the caller provided them. To avoid this issue the enumerator_t interface has been changed and the signature of the callback functions for enumerator_create_filter() and two methods on linked_list_t have been changed. Refer to the developer notes below for details. *Adds support for fuzzing the certificate parser provided by the default plugins (x509, pem, gmp etc.) on Google's OSS-Fuzz infrastructure (or generally with libFuzzer). Several issues found while fuzzing these plugins were fixed. *Two new options have been added to charon's retransmission settings: retransmit_limit and retransmit_jitter. The former adds an upper limit to the calculated retransmission timeout, the latter randomly reduces it. Refer to Retransmission for details. *A bug in swanctl's --load-creds command was fixed that caused unencrypted private keys to get unloaded if the command was called multiple times. The load-key VICI command now returns the key ID of the loaded key on success. *The credential manager now enumerates local credential sets before global ones. This means certificates supplied by the peer will now be preferred over certificates with the same identity that may be locally stored (e.g. in the certificate cache). *Adds support for hardware offload of IPsec SAs as introduced by Linux 4.11 for specific hardware that supports this. *The pki tool loads the curve25519 plugin by default.

Changes in version 5.3.4: * Fixed an authentication bypass vulnerability in the eap-mschapv2 plugin that was caused by insufficient verification of the internal state when handling MSCHAPv2 Success messages received by the client. This vulnerability has been registered as CVE-2015-8023. * The sha3 plugin implements the SHA3 Keccak-F1600 hash algorithm family. Within the strongSwan framework SHA3 is currently used for BLISS signatures only because the OIDs for other signature algorithms haven't been defined yet. Also the use of SHA3 for IKEv2 has not been standardized yet. Changes in version 5.3.3: * Added support for the ChaCha20/Poly1305 AEAD cipher specified in RFC 7539 and RFC 7634 using the chacha20poly1305 ike/esp proposal keyword. The new chapoly plugin implements the cipher, if possible SSE-accelerated on x86/x64 architectures. It is usable both in IKEv2 and the strongSwan libipsec ESP backend. On Linux 4.2 or newer the kernel-netlink plugin can configure the cipher for ESP SAs. * The vici interface now supports the configuration of auxiliary certification authority information as CRL and OCSP URIs. * In the bliss plugin the c_indices derivation using a SHA-512 based random oracle has been fixed, generalized and standardized by employing the MGF1 mask generation function with SHA-512. As a consequence BLISS signatures unsing the improved oracle are not compatible with the earlier implementation. * Support for auto=route with right=%any for transport mode connections has been added (the ikev2/trap-any scenario provides examples). * The starter daemon does not flush IPsec policies and SAs anymore when it is stopped. Already existing duplicate policies are now overwritten by the IKE daemon when it installs its policies. * Init limits (like charon.init_limit_half_open) can now optionally be enforced when initiating SAs via VICI. For this, IKE_SAs initiated by the daemon are now also counted as half open SAs, which, as a side-effect, fixes the status output while connecting (e.g. in ipsec status). * Symmetric configuration of EAP methods in left|rightauth is now possible when mutual EAP-only authentication is used (previously, the client had to configure rightauth=eap or rightauth=any, which prevented it from using this same config as responder). * The initiator flag in the IKEv2 header is compared again (wasn't the case since 5.0.0) and packets that have the flag set incorrectly are again ignored. * Implemented a demo Hardcopy Device IMC/IMV pair based on the "Hardcopy Device Health Assessment Trusted Network Connect Binding" (HCD-TNC) document drafted by the IEEE Printer Working Group (PWG). * Fixed IF-M segmentation which failed in the presence of multiple small attributes in front of a huge attribute to be segmented. Changes in version 5.3.2: * Fixed a vulnerability that allowed rogue servers with a valid certificate accepted by the client to trick it into disclosing its username and even password (if the client accepts EAP-GTC). This was caused because constraints against the responder's authentication were enforced too late. This vulnerability has been registered as CVE-2015-4171. Changes in version 5.3.1: * Fixed a denial-of-service and potential remote code execution vulnerability triggered by IKEv1/IKEv2 messages that contain payloads for the respective other IKE version. Such payload are treated specially since 5.2.2 but because they were still identified by their original payload type they were used as such in some places causing invalid function pointer dereferences. The vulnerability has been registered as CVE-2015-3991. * The new aesni plugin provides CBC, CTR, XCBC, CMAC, CCM and GCM crypto primitives for AES-128/192/256. The plugin requires AES-NI and PCLMULQDQ instructions and works on both x86 and x64 architectures. It provides superior crypto performance in userland without any external libraries. Changes in version 5.3.0: * Added support for IKEv2 make-before-break reauthentication. By using a global CHILD_SA reqid allocation mechanism, charon supports overlapping CHILD_SAs. This allows the use of make-before-break instead of the previously supported break-before-make reauthentication, avoiding connectivity gaps during that procedure. As the new mechanism may fail with peers not supporting it (such as any previous strongSwan release) it must be explicitly enabled using the charon.make_before_break strongswan.conf option. * Support for "Signature Authentication in IKEv2" (RFC 7427) has been added. This allows the use of stronger hash algorithms for public key authentication. By default, signature schemes are chosen based on the strength of the signature key, but specific hash algorithms may be configured in leftauth. * Key types and hash algorithms specified in rightauth are now also checked against IKEv2 signature schemes. If such constraints are used for certificate chain validation in existing configurations, in particular with peers that don't support RFC 7427, it may be necessary to disable this feature with the charon.signature_authentication_constraints setting, because the signature scheme used in classic IKEv2 public key authentication may not be strong enough. * The new connmark plugin allows a host to bind conntrack flows to a specific CHILD_SA by applying and restoring the SA mark to conntrack entries. This allows a peer to handle multiple transport mode connections coming over the same NAT device for client-initiated flows. A common use case is to protect L2TP/IPsec, as supported by some systems. * The forecast plugin can forward broadcast and multicast messages between connected clients and a LAN. For CHILD_SA using unique marks, it sets up the required Netfilter rules and uses a multicast/broadcast listener that forwards such messages to all connected clients. This plugin is designed for Windows 7 IKEv2 clients, which announces its services over the tunnel if the negotiated IPsec policy allows it. * For the vici plugin a Python Egg has been added to allow Python applications to control or monitor the IKE daemon using the VICI interface, similar to the existing ruby gem. The Python library has been contributed by Björn Schuberg. * EAP server methods now can fulfill public key constraints, such as rightcert or rightca. Additionally, public key and signature constraints can be specified for EAP methods in the rightauth keyword. Currently the EAP-TLS and EAP-TTLS methods provide verification details to constraints checking. * Upgrade of the BLISS post-quantum signature algorithm to the improved BLISS-B variant. Can be used in conjunction with the SHA256, SHA384 and SHA512 hash algorithms with SHA512 being the default. * The IF-IMV 1.4 interface now makes the IP address of the TNC access requestor as seen by the TNC server available to all IMVs. This information can be forwarded to policy enforcement points (e.g. firewalls or routers). * The new mutual tnccs-20 plugin parameter activates mutual TNC measurements in PB-TNC half-duplex mode between two endpoints over either a PT-EAP or PT-TLS transport medium. - Adjusted file lists and removed obsolete patches [- 0005-strongswan-5.2.2-5.3.0_unknown_payload.patch, - 0006-strongswan-5.1.0-5.3.1_enforce_remote_auth.patch, - 0007-strongswan-4.4.0-5.3.3_eap_mschapv2_state.patch] ------------------------------------------------------------------- Fri Nov 13 10:25:59 UTC 2015 - mt@suse.de - Applied upstream fix for a authentication bypass vulnerability in the eap-mschapv2 plugin (CVE-2015-8023,bsc#953817).

This identifier was used internally for DH groups with custom generator and prime. Because these arguments are missing when creating DH objects based on the KE payload an invalid pointer dereference occurred. This allowed an attacker to crash the IKE daemon with a single IKE_SA_INIT message containing such a KE payload. The vulnerability has been registered as CVE-2014-9221. * The left/rightid options in ipsec.conf, or any other identity in strongSwan, now accept prefixes to enforce an explicit type, such as email: or fqdn:. Note that no conversion is done for the remaining string, refer to ipsec.conf(5) for details. * The post-quantum Bimodal Lattice Signature Scheme (BLISS) can be used as an IKEv2 public key authentication method. The pki tool offers full support for the generation of BLISS key pairs and certificates. * Fixed mapping of integrity algorithms negotiated for AH via IKEv1. This could cause interoperability issues when connecting to older versions of charon. Changes in version 5.2.1: * The new charon-systemd IKE daemon implements an IKE daemon tailored for use with systemd. It avoids the dependency on ipsec starter and uses swanctl as configuration backend, building a simple and lightweight solution. It supports native systemd journal logging. * Support for IKEv2 fragmentation as per RFC 7383 has been added. Like IKEv1 fragmentation it can be enabled by setting fragmentation=yes in ipsec.conf. * Support of the TCG TNC IF-M Attribute Segmentation specification proposal. All attributes can be segmented. Additionally TCG/SWID Tag, TCG/SWID Tag ID and IETF/Installed Packages attributes can be processed incrementally on a per segment basis. * The new ext-auth plugin calls an external script to implement custom IKE_SA authorization logic, courtesy of Vyronas Tsingaras. * For the vici plugin a ruby gem has been added to allow ruby applications to control or monitor the IKE daemon. The vici documentation has been updated to include a description of the available operations and some simple examples using both the libvici C interface and the ruby gem. Changes in version 5.2.0: * strongSwan has been ported to the Windows platform. Using a MinGW toolchain, many parts of the strongSwan codebase run natively on Windows 7 / 2008 R2 and newer releases. charon-svc implements a Windows IKE service based on libcharon, the kernel-iph and kernel-wfp plugins act as networking and IPsec backend on the Windows platform. socket-win provides a native IKE socket implementation, while winhttp fetches CRL and OCSP information using the WinHTTP API. * The new vici plugin provides a Versatile IKE Configuration Interface for charon. Using the stable IPC interface, external applications can configure, control and monitor the IKE daemon. Instead of scripting the ipsec tool and generating ipsec.conf, third party applications can use the new interface for more control and better reliability. * Built upon the libvici client library, swanctl implements the first user of the VICI interface. Together with a swanctl.conf configuration file, connections can be defined, loaded and managed. swanctl provides a portable, complete IKE configuration and control interface for the command line. The first six swanctl example scenarios have been added. * The SWID IMV implements a JSON-based REST API which allows the exchange of SWID tags and Software IDs with the strongTNC policy manager. * The SWID IMC can extract all installed packages from the dpkg (Debian, Ubuntu, Linux Mint etc.), rpm (Fedora, RedHat, OpenSUSE, etc.), or pacman (Arch Linux, Manjaro, etc.) package managers, respectively, using the swidGenerator (https://github.com/strongswan/swidGenerator) which generates SWID tags according to the new ISO/IEC 19770-2:2014 standard. * All IMVs now share the access requestor ID, device ID and product info of an access requestor via a common imv_session object. * The Attestation IMC/IMV pair supports the IMA-NG measurement format introduced with the Linux 3.13 kernel. * The aikgen tool generates an Attestation Identity Key bound to a TPM. * Implemented the PT-EAP transport protocol (RFC 7171) for Trusted Network Connect. * The ipsec.conf replay_window option defines connection specific IPsec replay windows.

The openac utility has been removed in favor of the new pki functionality. - The libtls TLS 1.2 implementation as used by EAP-(T)TLS and other protocols has been extended by AEAD mode support, currently limited to AES-GCM. - Fixed an issue where CRL/OCSP trustchain validation broke enforcing CA constraints - Limited OCSP signing to specific certificates to improve performance - authKeyIdentifier is not added to self-signed certificates anymore - Fixed the comparison of IKE configs if only the cipher suites were different ------------------------------------------------------------------- Wed Apr 2 05:53:21 UTC 2014 - mt@suse.de - Updated to strongSwan 5.1.2 providing the following changes: - A new default configuration file layout is introduced. The new default strongswan.conf file mainly includes config snippets from the strongswan.d and strongswan.d/charon directories (the latter containing snippets for all plugins). The snippets, with commented defaults, are automatically generated and installed, if they don't exist yet. Also installed in $prefix/share/strongswan/templates so existing files can be compared to the current defaults. - As an alternative to the non-extensible charon.load setting, the plugins to load in charon (and optionally other applications) can now be determined via the charon.plugins.<name>.load setting for each plugin (enabled in the new default strongswan.conf file via the charon.load_modular option). The load setting optionally takes a numeric priority value that allows reordering the plugins (otherwise the default plugin order is preserved). - All strongswan.conf settings that were formerly defined in library specific "global" sections are now application specific (e.g. settings for plugins in libstrongswan.plugins can now be set only for charon in charon.plugins). The old options are still supported, which now allows to define defaults for all applications in the libstrongswan section. - The ntru libstrongswan plugin supports NTRUEncrypt as a post-quantum computer IKE key exchange mechanism. The implementation is based on the ntru-crypto library from the NTRUOpenSourceProject. The supported security strengths are ntru112, ntru128, ntru192, and ntru256. Since the private DH group IDs 1030..1033 have been assigned, the strongSwan Vendor ID must be sent in order to use NTRU (charon.send_vendor_id = yes). - Defined a TPMRA remote attestation workitem and added support for it to the Attestation IMV. - Compatibility issues between IPComp (compress=yes) and leftfirewall=yes as well as multiple subnets in left|rightsubnet have been fixed. - When enabling its "session" strongswan.conf option, the xauth-pam plugin opens and closes a PAM session for each established IKE_SA. Patch courtesy of Andrea Bonomi. - The strongSwan unit testing framework has been rewritten without the "check" dependency for improved flexibility and portability. It now properly supports multi-threaded and memory leak testing and brings a bunch of new test cases. ------------------------------------------------------------------- Fri Nov 1 12:28:39 UTC 2013 - mt@suse.de - Updated to strongSwan 5.1.1 minor release addressing two security fixes (bnc#847506,CVE-2013-6075, bnc#847509,CVE-2013-6076): - Fixed a denial-of-service vulnerability and potential authorization bypass triggered by a crafted ID_DER_ASN1_DN ID payload. The cause is an insufficient length check when comparing such identities. The vulnerability has been registered as CVE-2013-6075. - Fixed a denial-of-service vulnerability triggered by a crafted IKEv1 fragmentation payload. The cause is a NULL pointer dereference. The vulnerability has been registered as CVE-2013-6076. - The lean stand-alone pt-tls-client can set up a RFC 6876 PT-TLS session with a strongSwan policy enforcement point which uses the tnc-pdp charon plugin. - The new TCG TNC SWID IMC/IMV pair supports targeted SWID requests for either full SWID Tag or concise SWID Tag ID inventories. - The XAuth backend in eap-radius now supports multiple XAuth exchanges for different credential types and display messages. All user input gets concatenated and verified with a single User-Password RADIUS attribute on the AAA. With an AAA supporting it, one for example can implement Password+Token authentication with proper dialogs on iOS and OS X clients. - charon supports IKEv1 Mode Config exchange in push mode. The ipsec.conf modeconfig=push option enables it for both client and server, the same way as pluto used it. - Using the "ah" ipsec.conf keyword on both IKEv1 and IKEv2 connections, charon can negotiate and install Security Associations integrity-protected by the Authentication Header protocol. Supported are plain AH(+IPComp) SAs only, but not the deprecated RFC2401 style ESP+AH bundles. - The generation of initialization vectors for IKE and ESP (when using libipsec) is now modularized and IVs for e.g. AES-GCM are now correctly allocated sequentially, while other algorithms like AES-CBC still use random IVs. - The left and right options in ipsec.conf can take multiple address ranges and subnets. This allows connection matching against a larger set of addresses, for example to use a different connection for clients connecting from a internal network. - For all those who have a queasy feeling about the NIST elliptic curve set, the Brainpool curves introduced for use with IKE by RFC 6932 might be a more trustworthy alternative. - The kernel-libipsec userland IPsec backend now supports usage statistics, volume based rekeying and accepts ESPv3 style TFC padded packets. - With two new strongswan.conf options fwmarks can be used to implement host-to-host tunnels with kernel-libipsec. - load-tester supports transport mode connections and more complex traffic selectors, including such using unique ports for each tunnel. - The new dnscert plugin provides support for authentication via CERT RRs that are protected via DNSSEC. The plugin was created by Ruslan N. Marchenko. - The eap-radius plugin supports forwarding of several Cisco Unity specific RADIUS attributes in corresponding configuration payloads. - Database transactions are now abstracted and implemented by the two backends. If you use MySQL make sure all tables use the InnoDB engine. - libstrongswan now can provide an experimental custom implementation of the printf family functions based on klibc if neither Vstr nor glibc style printf hooks are available. This can avoid the Vstr dependency on some systems at the cost of slower and less complete printf functions. - Adjusted file lists: this version installs the pki utility and manuals in common /usr directories and additional ipsec/pt-tls-client helper. ------------------------------------------------------------------- Mon Aug 5 13:48:11 UTC 2013 - mt@suse.de - Updated to strongSwan 5.1.0 release (bnc#833278, CVE-2013-5018): - Fixed a denial-of-service vulnerability triggered by specific XAuth usernames and EAP identities (since 5.0.3), and PEM files (since 4.1.11). The crash was caused by insufficient error handling in the is_asn1() function. The vulnerability has been registered as CVE-2013-5018. - The new charon-cmd command line IKE client can establish road warrior connections using IKEv1 or IKEv2 with different authentication profiles. It does not depend on any configuration files and can be configured using a few simple command line options. - The kernel-pfroute networking backend has been greatly improved. It now can install virtual IPs on TUN devices on OS X and FreeBSD, allowing these systems to act as a client in common road warrior scenarios. - The new kernel-libipsec plugin uses TUN devices and libipsec to provide IPsec processing in userland on Linux, FreeBSD and Mac OS X. - The eap-radius plugin can now serve as an XAuth backend called xauth-radius, directly verifying XAuth credentials using RADIUS User-Name/User-Password attributes. This is more efficient than the existing xauth-eap+eap-radius combination, and allows RADIUS servers without EAP support to act as AAA backend for IKEv1. - The new osx-attr plugin installs configuration attributes (currently DNS servers) via SystemConfiguration on Mac OS X. The keychain plugin provides certificates from the OS X keychain service. - The sshkey plugin parses SSH public keys, which, together with the --agent option for charon-cmd, allows the use of ssh-agent for authentication. To configure SSH keys in ipsec.conf the left|rightrsasigkey options are replaced with left|rightsigkey, which now take public keys in one of three formats: SSH (RFC 4253, ssh: prefix), DNSKEY (RFC 3110, dns: prefix), and PKCS#1 (the default, no prefix). - Extraction of certificates and private keys from PKCS#12 files is now provided by the new pkcs12 plugin or the openssl plugin. charon-cmd (--p12) as well as charon (via P12 token in ipsec.secrets) can make use of this. - IKEv2 can now negotiate transport mode and IPComp in NAT situations. - IKEv2 exchange initiators now properly close an established IKE or CHILD_SA on error conditions using an additional exchange, keeping state in sync between peers. - Using a SQL database interface a Trusted Network Connect (TNC) Policy Manager can generate specific measurement workitems for an arbitrary number of Integrity Measurement Verifiers (IMVs) based on the history of the VPN user and/or device. - Several core classes in libstrongswan are now tested with unit tests. These can be enabled with --enable-unit-tests and run with 'make check'. Coverage reports can be generated with --enable-coverage and 'make coverage' (this disables any optimization, so it should not be enabled when building production releases). - The leak-detective developer tool has been greatly improved. It works much faster/stabler with multiple threads, does not use deprecated malloc hooks anymore and has been ported to OS X. - chunk_hash() is now based on SipHash-2-4 with a random key. This provides better distribution and prevents hash flooding attacks when used with hashtables. - All default plugins implement the get_features() method to define features and their dependencies. The plugin loader has been improved, so that plugins in a custom load statement can be ordered freely or to express preferences without being affected by dependencies between plugin features. - A centralized thread can take care for watching multiple file descriptors concurrently. This removes the need for a dedicated listener threads in various plugins. The number of "reserved" threads for such tasks has been reduced to about five, depending on the plugin configuration. - Plugins that can be controlled by a UNIX socket IPC mechanism gained network transparency. Third party applications querying these plugins now can use TCP connections from a different host. - libipsec now supports AES-GCM. ------------------------------------------------------------------- Tue Apr 30 12:48:44 UTC 2013 - mt@suse.de - Updated to strongSwan 5.0.4 release (bnc#815236, CVE-2013-2944): - Fixed a security vulnerability in the openssl plugin which was reported by Kevin Wojtysiak. The vulnerability has been registered as CVE-2013-2944. Before the fix, if the openssl plugin's ECDSA signature verification was used, due to a misinterpretation of the error code returned by the OpenSSL ECDSA_verify() function, an empty or zeroed signature was accepted as a legitimate one. Refer to our blog for details. - The handling of a couple of other non-security relevant OpenSSL return codes was fixed as well. - The tnc_ifmap plugin now publishes virtual IPv4 and IPv6 addresses via its TCG TNC IF-MAP 2.1 interface. - The charon.initiator_only strongswan.conf option causes charon to ignore IKE initiation requests. - The openssl plugin can now use the openssl-fips library. The version 5.0.3 provides new ipseckey plugin, enabling authentication based on trustworthy public keys stored as IPSECKEY resource records in the DNS and protected by DNSSEC and new openssl plugin using the AES-NI accelerated version of AES-GCM if the hardware supports it. See http://wiki.strongswan.org/projects/strongswan/wiki/Changelog50 for a list of all changes since the 5.0.1 release. ------------------------------------------------------------------- Thu Nov 29 19:13:40 CET 2012 - sbrabec@suse.cz - Verify GPG signature. ------------------------------------------------------------------- Fri Nov 16 04:02:32 UTC 2012 - crrodriguez@opensuse.org - Fix systemd unit dir ------------------------------------------------------------------- Wed Oct 31 15:25:16 UTC 2012 - mt@suse.de - Updated to strongSwan 5.0.1 release. Changes digest: - Introduced the sending of the standard IETF Assessment Result PA-TNC attribute by all strongSwan Integrity Measurement Verifiers. - Extended PTS Attestation IMC/IMV pair to provide full evidence of the Linux IMA measurement process. All pertinent file information of a Linux OS can be collected and stored in an SQL database. - The PA-TNC and PB-TNC protocols can now process huge data payloads. - The xauth-pam backend can authenticate IKEv1 XAuth and Hybrid authenticated clients against any PAM service. - The new unity plugin brings support for some parts of the IKEv1 Cisco Unity Extensions. - The kernel-netlink plugin supports the new strongswan.conf option charon.install_virtual_ip_on. - Job handling in controller_t was fixed, which occasionally caused crashes on ipsec up/down. - Fixed transmission EAP-MSCHAPv2 user name if it contains a domain part. Changes digest from strongSwan 5.0.0 version: * The charon IKE daemon gained experimental support for the IKEv1 protocol. Pluto has been removed from the 5.x series. * The NetworkManager charon plugin of previous releases is now provided by a separate executable (charon-nm) and it should work again with NM 0.9. * scepclient was updated and it now works fine with Windows Server 2008 R2. For full list of the changes, please read the NEWS file shipped in the strongswan-doc package or online: http://wiki.strongswan.org/projects/strongswan/wiki/Changelog50 - Adopted spec file, enabled several plugins, e.g.: ccm, certexpire, coupling, ctr, duplicheck, eap-dynamic, eap-peap, eap-tls, eap-tnc, eap-ttls, gcm, nonce, radattr, tnc, tnccs, unity, xauth-eap and pam. - Changed to install strongswan.service with alias to ipsec.service instead of the /etc/init.d/ipsec init script on openSUSE > 12.2. ------------------------------------------------------------------- Fri Sep 7 08:36:57 UTC 2012 - mt@suse.de - Applied upstream patch adjusting an internal thread id causing charon keying daemon start failure (bnc#779038,strongswan#198): openssl: Ensure the thread ID is never zero This might otherwise cause problems because OpenSSL tries to lock mutexes recursively if it assumes the lock is held by a different thread e.g. during FIPS initialization. See http://wiki.strongswan.org/issues/198 for more informations. ------------------------------------------------------------------- Thu May 31 16:08:43 UTC 2012 - mt@suse.com - Updated to strongSwan 4.6.4 release: - Fixed a security vulnerability in the gmp plugin. If this plugin was used for RSA signature verification an empty or zeroed signature was handled as a legitimate one (bnc#761325, CVE-2012-2388). - Fixed several issues with reauthentication and address updates. ------------------------------------------------------------------- Thu May 10 09:15:38 UTC 2012 - mt@suse.com - Updated to strongSwan 4.6.3 release: - The tnc-pdp plugin implements a RADIUS server interface allowing a strongSwan TNC server to act as a Policy Decision Point. - The eap-radius authentication backend enforces Session-Timeout attributes using RFC4478 repeated authentication and acts upon RADIUS Dynamic Authorization extensions, RFC 5176. Currently supported are disconnect requests and CoA messages containing a Session-Timeout. - The eap-radius plugin can forward arbitrary RADIUS attributes from and to clients using custom IKEv2 notify payloads. The new radattr plugin reads attributes to include from files and prints received attributes to the console. - Added support for untruncated MD5 and SHA1 HMACs in ESP as used in RFC 4595. - The cmac plugin implements the AES-CMAC-96 and AES-CMAC-PRF-128 algorithms as defined in RFC 4494 and RFC 4615, respectively. - The resolve plugin automatically installs nameservers via resolvconf(8), if it is installed, instead of modifying /etc/resolv.conf directly. - The IKEv2 charon daemon supports now raw RSA public keys in RFC 3110 DNSKEY and PKCS#1 file format. - The farp plugin sends ARP responses for any tunneled address, not only virtual IPs. - Charon resolves hosts again during additional keying tries. - Fixed switching back to original address pair during MOBIKE. - When resending IKE_SA_INIT with a COOKIE charon reuses the previous DH value, as specified in RFC 5996. This has an effect on the lifecycle of diffie_hellman_t, see source:src/libcharon/sa/keymat.h#39 for details. - COOKIEs are now kept enabled a bit longer to avoid certain race conditions the commit message to 1b7debcc has some details. - The new stroke user-creds command allows to set username/password for a connection. - strongswan.conf option added to set identifier for syslog(3) logging. - Added a workaround for null-terminated XAuth secrets (as sent by Android 4). ------------------------------------------------------------------- Sat Mar 3 00:10:34 UTC 2012 - tabraham@novell.com - Updated to strongSwan 4.6.2 release: Changes in 4.6.2: - Upgraded the TCG IF-IMC and IF-IMV C API to the upcoming version 1.3 which supports IF-TNCCS 2.0 long message types, the exclusive flags and multiple IMC/IMV IDs. Both the TNC Client and Server as well as the "Test", "Scanner", and "Attestation" IMC/IMV pairs were updated. - Fully implemented the "TCG Attestation PTS Protocol: Binding to IF-M" standard (TLV-based messages only). TPM-based remote attestation of Linux IMA (Integrity Measurement Architecture) possible. Measurement reference values are automatically stored in an SQLite database. - The EAP-RADIUS authentication backend supports RADIUS accounting. It sends start/stop messages containing Username, Framed-IP and Input/Output-Octets attributes and has been tested against FreeRADIUS and Microsoft NPS. - Added support for PKCS#8 encoded private keys via the libstrongswan pkcs8 plugin. This is the default format used by some OpenSSL tools since version 1.0.0 (e.g. openssl req with -keyout). - Added session resumption support to the strongSwan TLS stack. ------------------------------------------------------------------- Wed Feb 15 13:31:40 UTC 2012 - mt@suse.com - Updated to strongSwan 4.6.1 release: Changes in 4.6.1: - Because of changing checksums before and after installation which caused the integrity tests to fail we avoided directly linking libsimaka, libtls and libtnccs to those libcharon plugins which make use of these dynamiclibraries. Instead we linked the libraries to the charon daemon. Unfortunately Ubuntu 11.10 activated the --as-needed ld option which discards explicit links to dynamic libraries that are not actually used by the charon daemon itself, thus causing failures during the loading of the plugins which depend on these libraries for resolving external symbols. - Therefore our approach of computing integrity checksums for plugins had to be changed radically by moving the hash generation from the compilation to the post-installation phase. Changes in 4.6.0: - The new libstrongswan certexpire plugin collects expiration information of all used certificates and exports them to CSV files. It either directly exports them or uses cron style scheduling for batch exports. - Starter passes unresolved hostnames to charon, allowing it to do name resolution not before the connection attempt. This is especially useful with connections between hosts using dynamic IP addresses. Thanks to Mirko Parthey for the initial patch. - The android plugin can now be used without the Android frontend patch and provides DNS server registration and logging to logcat. - Pluto and starter (plus stroke and whack) have been ported to Android. - Support for ECDSA private and public key operations has been added to the pkcs11 plugin. The plugin now also provides DH and ECDH via PKCS#11 and can use tokens as random number generators (RNG). By default only private key operations are enabled, more advanced features have to be enabled by their option in strongswan.conf. This also applies to public key operations (even for keys not stored on the token) which were enabled by default before. - The libstrongswan plugin system now supports detailed plugin dependencies. Many plugins have been extended to export its capabilities and requirements. This allows the plugin loader to resolve plugin loading order automatically, and in future releases, to dynamically load the required features on demand. Existing third party plugins are source (but not binary) compatible if they properly initialize the new get_features() plugin function to NULL. - The tnc-ifmap plugin implements a TNC IF-MAP 2.0 client which can deliver metadata about IKE_SAs via a SOAP interface to a MAP server. The tnc-ifmap plugin requires the Apache Axis2/C library. - Merged patches, changed strongswan-doc to be a noarch package. - Fixed rpmlint runlevel & fsf warnings, updated rpmlintrc ------------------------------------------------------------------- Mon Feb 6 10:27:00 UTC 2012 - aj@suse.de - Only glib.h can be included, fix compilation. ------------------------------------------------------------------- Wed Dec 21 10:31:49 UTC 2011 - coolo@suse.com - remove call to suse_update_config (very old work around) ------------------------------------------------------------------- Mon Sep 12 09:26:51 UTC 2011 - coolo@suse.com - remove _service file, too fragile ------------------------------------------------------------------- Mon Sep 12 08:24:36 UTC 2011 - mt@suse.com - Fixed version in last changelog entry ------------------------------------------------------------------- Thu Sep 8 16:06:46 UTC 2011 - mt@suse.com - Updated to strongSwan 4.5.3 release, changes overview since 4.5.2: * Our private libraries (e.g. libstrongswan) are not installed directly in prefix/lib anymore. Instead a subdirectory is used (prefix/lib/ipsec/ by default). The plugins directory is also moved from libexec/ipsec/ to that directory. * The dynamic IMC/IMV libraries were moved from the plugins directory to a new imcvs directory in the prefix/lib/ipsec/ subdirectory. * Job priorities were introduced to prevent thread starvation caused by too many threads handling blocking operations (such as CRL fetching). * Two new strongswan.conf options allow to fine-tune performance on IKEv2 gateways by dropping IKE_SA_INIT requests on high load. * IKEv2 charon daemon supports PASS and DROP shunt policies preventing traffic to go through IPsec connections. Installation of the shunt policies either via the XFRM netfilter or PFKEYv2 IPsec kernel interfaces. * The history of policies installed in the kernel is now tracked so that e.g. trap policies are correctly updated when reauthenticated SAs are terminated. * IMC/IMV Scanner pair implementing the RFC 5792 PA-TNC (IF-M) protocol. Using "netstat -l" the IMC scans open listening ports on the TNC client and sends a port list to the IMV which based on a port policy decides if the client is admitted to the network. * IMC/IMV Test pair implementing the RFC 5792 PA-TNC (IF-M) protocol. * The IKEv2 close action does not use the same value as the ipsec.conf dpdaction setting, but the value defined by its own closeaction keyword. The action is triggered if the remote peer closes a CHILD_SA unexpectedly. - Fixed some fmt warnings in libchecksum, adopted paths in the spec file ------------------------------------------------------------------- Sun May 29 16:37:00 UTC 2011 - jcnengel@googlemail.com - Updated to strongSwan 4.5.2 release, changes overview since 4.5.1: * The whitelist plugin for the IKEv2 daemon maintains an in-memory identity whitelist. Any connection attempt of peers not whitelisted will get rejected. The 'ipsec whitelist' utility provides a simple command line frontend for whitelist administration. * The duplicheck plugin provides a specialized form of duplicate checking, doing a liveness check on the old SA and optionally notify a third party application about detected duplicates. * The coupling plugin permanently couples two or more devices by limiting authentication to previously used certificates. * In the case that the peer config and child config don't have the same name (usually in SQL database defined connections), ipsec up|route <peer config> starts|routes all associated child configs and ipsec up|route <child config> only starts|routes the specific child config. * fixed the encoding and parsing of X.509 certificate policy statements (CPS). * Duncan Salerno contributed the eap-sim-pcsc plugin implementing a pcsc-lite based SIM card backend. * The eap-peap plugin implements the EAP PEAP protocol. Interoperates successfully with a FreeRADIUS server and Windows 7 Agile VPN clients. * The IKEv2 daemon charon rereads strongswan.conf on SIGHUP and instructs all plugins to reload. Currently only the eap-radius and the attr plugins support configuration reloading. * Added userland support to the IKEv2 daemon for Extended Sequence Numbers support coming with Linux 2.6.39. To enable ESN on a connection, add the 'esn' keyword to the proposal. The default proposal uses 32-bit sequence numbers only ('noesn'), and the same value is used if no ESN mode is specified. To negotiate ESN support with the peer, include both, e.g. esp=aes128-sha1-esn-noesn. * In addition to ESN, Linux 2.6.39 gained support for replay windows larger than 32 packets. The new global strongswan.conf option 'charon.replay_window' configures the size of the replay window, in packets. ------------------------------------------------------------------- Mon Mar 14 10:59:32 UTC 2011 - mt@suse.de - Updated to strongSwan 4.5.1 release, changes overview since 4.5.0: * Implements RFC 5793 Posture Broker Protocol (BP) * Re-implemented TNCCS 1.1 protocol * Allows to store IKE and ESP proposals in an SQL database * Allows to store CRL and OCSP cert points in an SQL database * New 'include' statement in strongswan.conf allows recursions * Modifications of strongswan.conf parser, cause syntax attr plugin syntax changes. * ipsec listalgs now appends the plugin registering an algo * Adds support for Traffic Flow Confidentiality with Linux 2.6.38 * New af-alg plugin allows to use new primitives in 2.6.38 crypto api and removes the need for additional userland implementations. * IKEv2 daemon supports the INITIAL_CONTACT notify * conftest conformance testing framework * new constraints plugin provides advanced X.509 constraint checking * left/rightauth ipsec.conf keywords accept minimum strengths * basic support for delta CRLs See the NEWS file or http://download.strongswan.org/CHANGES4.txt for a detailed description of the changes. ------------------------------------------------------------------- Mon Nov 22 09:05:30 UTC 2010 - mt@suse.de - Cleaned up spec file; use with_mysql,sqlite,gcrypt,nm flags - Disabled tests sub-package with load-tester and test-vectors plugins by default using a with_tests flag (causes load error in "ipsec pki" when enabled but the package is not installed). ------------------------------------------------------------------- Tue Nov 16 12:01:46 UTC 2010 - mt@suse.de - Updated to strongSwan 4.5.0 release, changes since 4.4.1 are: * IMPORTANT: the default keyexchange mode 'ike' is changing with release 4.5 from 'ikev1' to 'ikev2', thus commemorating the five year anniversary of the IKEv2 RFC 4306 and its mature successor RFC 5996. The time has definitively come for IKEv1 to go into retirement and to cede its place to the much more robust, powerful and versatile IKEv2 protocol! * Added new ctr, ccm and gcm plugins providing Counter, Counter with CBC-MAC and Galois/Counter Modes based on existing CBC implementations. These new plugins bring support for AES and Camellia Counter and CCM algorithms and the AES GCM algorithms for use in IKEv2. * The new pkcs11 plugin brings full Smartcard support to the IKEv2 daemon and the pki utility using one or more PKCS#11 libraries. It currently supports RSA private and public key operations and loads X.509 certificates from tokens. * Implemented a general purpose TLS stack based on crypto and credential primitives of libstrongswan. libtls supports TLS versions 1.0, 1.1 and 1.2, ECDHE-ECDSA/RSA, DHE-RSA and RSA key exchange algorithms and RSA/ECDSA based client authentication. * Based on libtls, the eap-tls plugin brings certificate based EAP authentication for client and server. It is compatible to Windows 7 IKEv2 Smartcard authentication and the OpenSSL based FreeRADIUS EAP-TLS backend. * Implemented the TNCCS 1.1 Trusted Network Connect protocol using the libtnc library on the strongSwan client and server side via the tnccs_11 plugin and optionally connecting to a TNC@FHH-enhanced FreeRADIUS AAA server. Depending on the resulting TNC Recommendation, strongSwan clients are granted access to a network behind a strongSwan gateway (allow), are put into a remediation zone (isolate) or are blocked (none), respectively. Any number of Integrity Measurement Collector/Verifier pairs can be attached via the tnc-imc and tnc-imv charon plugins. * The IKEv1 daemon pluto now uses the same kernel interfaces as the IKEv2 daemon charon. As a result of this, pluto now supports xfrm marks which were introduced in charon with 4.4.1. * The RADIUS plugin eap-radius now supports multiple RADIUS servers for redundant setups. Servers are selected by a defined priority, server load and availability. * The simple led plugin controls hardware LEDs through the Linux LED subsystem. It currently shows activity of the IKE daemon and is a good example how to implement a simple event listener. * Improved MOBIKE behavior in several corner cases, for instance, if the initial responder moves to a different address. * Fixed left-/rightnexthop option, which was broken since 4.4.0. * Fixed a bug not releasing a virtual IP address to a pool if the XAUTH identity was different from the IKE identity. * Fixed the alignment of ModeConfig messages on 4-byte boundaries in the case where the attributes are not a multiple of 4 bytes (e.g. Cisco's UNITY_BANNER). * Fixed the interoperability of the socket_raw and socket_default charon plugins. * Added man page for strongswan.conf - Adopted spec file, removed obsolete error range patch. ------------------------------------------------------------------- Tue Aug 10 11:43:38 UTC 2010 - mt@suse.de - Updated to strongSwan 4.4.1 release, changes since 4.4.0 are: * Support of xfrm marks in IPsec SAs and IPsec policies introduced with the Linux 2.6.34 kernel. For details see the example scenarios ikev2/nat-two-rw-mark, ikev2/rw-nat-mark-in-out and ikev2/net2net-psk-dscp. * The PLUTO_MARK_IN and PLUTO_ESP_ENC environment variables can be used in a user-specific updown script to set marks on inbound ESP or ESP_IN_UDP packets. * The openssl plugin now supports X.509 certificate and CRL functions. * OCSP/CRL checking in IKEv2 has been moved to the revocation plugin, enabled by default. Plase update manual load directives in strongswan.conf. * RFC3779 ipAddrBlock constraint checking has been moved to the addrblock plugin, disabled by default. Enable it and update manual load directives in strongswan.conf, if required. * The pki utility supports CRL generation using the --signcrl command. * The ipsec pki --self, --issue and --req commands now support output in PEM format using the --outform pem option. * The major refactoring of the IKEv1 Mode Config functionality now allows the transport and handling of any Mode Config attribute. * The RADIUS proxy plugin eap-radius now supports multiple servers. Configured servers are chosen randomly, with the option to prefer a specific server. Non-responding servers are degraded by the selection process. * The ipsec pool tool manages arbitrary configuration attributes stored in an SQL database. ipsec pool --help gives the details. * The new eap-simaka-sql plugin acts as a backend for EAP-SIM and EAP-AKA, reading triplets/quintuplets from an SQL database. * The High Availability plugin now supports a HA enabled in-memory address pool and Node reintegration without IKE_SA rekeying. The latter allows clients without IKE_SA rekeying support to keep connected during reintegration. Additionally, many other issues have been fixed in the ha plugin. * Fixed a potential remote code execution vulnerability resulting from the misuse of snprintf(). The vulnerability is exploitable by unauthenticated users. - Removed obsolete snprintf security fix, adopted spec file - Enabled the eap-sim,eap-sim-file,eap-simaka-sql,eap-simaka-reauth, eap-simaka-pseudonym,eap-aka-3gpp2,md4,blowfish,addrblock plugins. - Enabled the mysql, sqlite, load-tester and test-vectors plugins, that are packaged into separate mysql,sqlite,tests sub packages. - Disabled sqlite plugin on SLE-10 -- sqlite3 lib is too old there. - Applied patch by Jiri Bohac fixing error-type range in parsing of NOTIFY payloads (RFC 4306, section 3.10.1). ------------------------------------------------------------------- Fri Jul 2 15:40:17 UTC 2010 - mt@suse.de - Applied upstream patch fixing snprintf flaws in the strongSwan IKE daemons exploitable by unauthenticated attackers using a crafted certificate or identification payload (bnc#615915). ------------------------------------------------------------------- Fri Jul 2 14:16:18 UTC 2010 - mt@suse.de - Added README.SUSE to source list in the spec file. ------------------------------------------------------------------- Fri May 14 19:19:04 UTC 2010 - mt@suse.de - Updated to strongSwan 4.4.0 release, changes since 4.3.6 are: * The IKEv2 High Availability plugin has been integrated. It provides load sharing and failover capabilities in a cluster of currently two nodes, based on an extend ClusterIP kernel module. More information is available at http://wiki.strongswan.org/projects/strongswan/wiki/HighAvailability. The development of the High Availability functionality was sponsored by secunet Security Networks AG. * Added IKEv1 and IKEv2 configuration support for the AES-GMAC authentication-only ESP cipher. Our aes_gmac kernel patch or a Linux 2.6.34 kernel is required to make AES-GMAC available via the XFRM kernel interface. * Added support for Diffie-Hellman groups 22, 23 and 24 to the gmp, gcrypt and openssl plugins, usable by both pluto and charon. The new proposal keywords are modp1024s160, modp2048s224 and modp2048s256. Thanks to Joy Latten from IBM for her contribution. * The IKEv1 pluto daemon supports RAM-based virtual IP pools using the rightsourceip directive with a subnet from which addresses are allocated. * The ipsec pki --gen and --pub commands now allow the output of private and public keys in PEM format using the --outform pem command line option. * The new DHCP plugin queries virtual IP addresses for clients from a DHCP server using broadcasts, or a defined server using the charon.plugins.dhcp.server strongswan.conf option. DNS/WINS server information is additionally served to clients if the DHCP server provides such information. The plugin is used in ipsec.conf configurations having rightsourceip set to %dhcp. * A new plugin called farp fakes ARP responses for virtual IP addresses handed out to clients from the IKEv2 daemon charon. The plugin lets a road-warrior act as a client on the local LAN if it uses a virtual IP from the responders subnet, e.g. acquired using the DHCP plugin. * The existing IKEv2 socket implementations have been migrated to the socket-default and the socket-raw plugins. The new socket-dynamic plugin binds sockets dynamically to ports configured via the left-/rightikeport ipsec.conf connection parameters. * The android charon plugin stores received DNS server information as "net.dns" system properties, as used by the Android platform. - Splitted package into strongswan-ipsec, that install the traditional ipsec service starter scripts, -ikev1 and -ikev2 installing daemons and -libs0, that contains the library and plugins. - Enabled dhcp, farp, ha, socket-dynamic, agent, eap and sql plugins. - Enabled NetworkManager nm plugin in a separate strongswan-nm package. ------------------------------------------------------------------- Tue Mar 2 21:42:10 CET 2010 - mt@suse.de - Updated to strongSwan 4.3.6 release, changes since 4.3.4 are: * The IKEv2 daemon supports RFC 3779 IP address block constraints carried as a critical X.509v3 extension in the peer certificate. * The ipsec pool --add|del dns|nbns command manages DNS and NBNS name server entries that are sent via the IKEv1 Mode Config or IKEv2 Configuration Payload to remote clients. * The Camellia cipher can be used as an IKEv1 encryption algorithm. * The IKEv1 and IKEV2 daemons now check certificate path length constraints. * The new ipsec.conf conn option "inactivity" closes a CHILD_SA if no traffic was sent or received within the given interval. To close the complete IKE_SA if its only CHILD_SA was inactive, set the global strongswan.conf option "charon.inactivity_close_ike" to yes. * More detailed IKEv2 EAP payload information in debug output * IKEv2 EAP-SIM and EAP-AKA share joint libsimaka library * Added required userland changes for proper SHA256 and SHA384/512 in ESP that will be introduced with Linux 2.6.33. The "sha256"/"sha2_256" keyword now configures the kernel with 128 bit truncation, not the non-standard 96 bit truncation used by previous releases. To use the old 96 bit truncation scheme, the new "sha256_96" proposal keyword has been introduced. * Fixed IPComp in tunnel mode, stripping out the duplicated outer header. This change makes IPcomp tunnel mode connections incompatible with previous releases; disable compression on such tunnels. * Fixed BEET mode connections on recent kernels by installing SAs with appropriate traffic selectors, based on a patch by Michael Rossberg. * Using extensions (such as BEET mode) and crypto algorithms (such as twofish, serpent, sha256_96) allocated in the private use space now require that we know its meaning, i.e. we are talking to strongSwan. Use the new "charon.send_vendor_id" option in strongswan.conf to let the remote peer know this is the case. * Experimental support for draft-eronen-ipsec-ikev2-eap-auth, where the responder omits public key authentication in favor of a mutual authentication method. To enable EAP-only authentication, set rightauth=eap on the responder to rely only on the MSK constructed AUTH payload. This not-yet standardized extension requires the strongSwan vendor ID introduced above. * The IKEv1 daemon ignores the Juniper SRX notification type 40001, thus allowing interoperability. * The IKEv1 pluto daemon can now use SQL-based address pools to deal out virtual IP addresses as a Mode Config server. The pool capability has been migrated from charon's sql plugin to a new attr-sql plugin which is loaded by libstrongswan and which can be used by both daemons either with a SQLite or MySQL database and the corresponding plugin. * Plugin names have been streamlined: EAP plugins now have a dash after eap (e.g. eap-sim), as it is used with the --enable-eap-sim ./configure option. Plugin configuration sections in strongswan.conf now use the same name as the plugin itself (i.e. with a dash). Make sure to update "load" directives and the affected plugin sections in existing strongswan.conf files. * The private/public key parsing and encoding has been split up into separate pkcs1, pgp, pem and dnskey plugins. The public key implementation plugins gmp, gcrypt and openssl can all make use of them. * The EAP-AKA plugin can use different backends for USIM/quintuplet calculations, very similar to the EAP-SIM plugin. The existing 3GPP2 software implementation has been migrated to a separate plugin. * The IKEv2 daemon charon gained basic PGP support. It can use locally installed peer certificates and can issue signatures based on RSA private keys. * The new 'ipsec pki' tool provides a set of commands to maintain a public key infrastructure. It currently supports operations to create RSA and ECDSA private/public keys, calculate fingerprints and issue or verify certificates. * Charon uses a monotonic time source for statistics and job queueing, behaving correctly if the system time changes (e.g. when using NTP). * In addition to time based rekeying, charon supports IPsec SA lifetimes based on processed volume or number of packets. They new ipsec.conf paramaters 'lifetime' (an alias to 'keylife'), 'lifebytes' and 'lifepackets' handle SA timeouts, while the parameters 'margintime' (an alias to rekeymargin), 'marginbytes' and 'marginpackets' trigger the rekeying before a SA expires. The existing parameter 'rekeyfuzz' affects all margins. * If no CA/Gateway certificate is specified in the NetworkManager plugin, charon uses a set of trusted root certificates preinstalled by distributions. The directory containing CA certificates can be specified using the --with-nm-ca-dir=path configure option. * Fixed the encoding of the Email relative distinguished name in left|rightid statements. * Fixed the broken parsing of PKCS#7 wrapped certificates by the pluto daemon. * Fixed smartcard-based authentication in the pluto daemon which was broken by the ECDSA support introduced with the 4.3.2 release. * A patch contributed by Heiko Hund fixes mixed IPv6 in IPv4 and vice versa tunnels established with the IKEv1 pluto daemon. * The pluto daemon now uses the libstrongswan x509 plugin for certificates and CRls and the struct id type was replaced by identification_t used by charon and the libstrongswan library. - Removed obsolete load_secrets patches, refreshed modprobe patch. - Corrected a time_t cast reported by rpmlint (timer.c:51) - Disabled libtoolize call and the gcrypt plugin on SLE 10. ------------------------------------------------------------------- Fri Sep 4 12:56:59 CEST 2009 - mt@suse.de - Fixed open failure debug message in load_secrets ------------------------------------------------------------------- Thu Sep 3 23:44:37 CEST 2009 - mt@suse.de - Applied patch fixing locking in ipsec.secrets inclusion. ------------------------------------------------------------------- Mon Aug 31 16:06:13 CEST 2009 - mt@suse.de - Updated to strongSwan 4.3.4 release: * IKEv2 charon daemon ported to FreeBSD and Mac OS X. Installation details can be found on wiki.strongswan.org. * ipsec statusall shows the number of bytes transmitted and received over ESP connections configured by the IKEv2 charon daemon. * The IKEv2 charon daemon supports include files in ipsec.secrets. - Removed obsolete ipsec.secrets include patch (bnc#524799) and patch to avoid libchecksum version. ------------------------------------------------------------------- Fri Aug 7 11:44:30 CEST 2009 - mt@suse.de - Applied patch implementing ipsec.secrets "include" directive support in charon (http://wiki.strongswan.org/issues/show/82, bnc#524799). ------------------------------------------------------------------- Mon Jul 27 13:40:57 CEST 2009 - mt@suse.de - Updated to strongSwan 4.3.3 release: * The configuration option --enable-integrity-test plus the strongswan.conf option libstrongswan.integrity_test = yes activate integrity tests of the IKE daemons charon and pluto, libstrongswan and all loaded plugins. Thus dynamic library misconfigurations and non-malicious file manipulations can be reliably detected. * The new default setting libstrongswan.ecp_x_coordinate_only=yes allows IKEv1 interoperability with MS Windows using the ECP DH groups 19 and 20. * The IKEv1 pluto daemon now supports the AES-CCM and AES-GCM ESP authenticated encryption algorithms. * The IKEv1 pluto daemon now supports V4 OpenPGP keys. * The RDN parser vulnerability discovered by Orange Labs research team was not completely fixed in version 4.3.2. Some more modifications had to be applied to the asn1_length() function to make it robust. - Enabled --enable-integrity-test configure option (new feature). - Removed patch to avoid plugin versions (accepted by upstream) and added patch to avoid version for new libchecksum library. - Added -Wno-pointer-sign -Wno-strict-aliasing CFLAGS in the spec. ------------------------------------------------------------------- Wed Jun 10 11:04:44 CEST 2009 - mt@suse.de - Updated to strongSwan 4.3.2 release, that fixes two asn1 parser DoS vulnerabilities and provides several new features, e.g.: * The new gcrypt plugin provides symmetric cipher, hasher, RNG, Diffie-Hellman and RSA crypto primitives using the LGPL licensed GNU gcrypt library. * libstrongswan features an integrated crypto selftest framework for registered algorithms. The test-vector plugin provides a first set of test vectors and allows pluto and charon to rely on tested crypto algorithms. * pluto can now use all libstrongswan plugins with the exception of x509 and xcbc. Thanks to the openssl plugin, the ECP Diffie- Hellman groups 19, 20, 21, 25, and 26 as well as ECDSA-256, ECDSA-384, and ECDSA-521 authentication can be used with IKEv1. * Applying their fuzzing tool, the Orange Labs vulnerability research team found another two DoS vulnerabilities, one in the rather old ASN.1 parser of Relative Distinguished Names (RDNs) and a second one in the conversion of ASN.1 UTCTIME and GENERALIZEDTIME strings to a time_t value. * The nm plugin now passes DNS/NBNS server information to NetworkManager, allowing a gateway administrator to set DNS/NBNS configuration on clients dynamically. * The nm plugin also accepts CA certificates for gateway authentication. If a CA certificate is configured, strongSwan uses the entered gateway address as its idenitity, requiring the gateways certificate to contain the same as subjectAltName. This allows a gateway administrator to deploy the same certificates to Windows 7 and NetworkManager clients. * The command ipsec purgeike deletes IKEv2 SAs that don't have a CHILD SA. The command ipsec down <conn>{n} deletes CHILD SA instance n of connection <conn> whereas ipsec down <conn>{*} deletes all CHILD SA instances. The command ipsec down <conn>[n] deletes IKE SA instance n of connection <conn> plus dependent CHILD SAs whereas ipsec down <conn>[*] deletes all IKE SA instances of connection <conn>. * Fixed a regression introduced in 4.3.0 where EAP authentication calculated the AUTH payload incorrectly. Further, the EAP-MSCHAPv2 MSK key derivation has been updated to be compatible with the Windows 7 Release Candidate. * Refactored installation of triggering policies. Routed policies are handled outside of IKE_SAs to keep them installed in any case. A tunnel gets established only once, even if initiation is delayed due network outages. * Improved the handling of multiple acquire signals triggered by the kernel. * Fixed two DoS vulnerabilities in the charon daemon that were discovered by fuzzing techniques: 1) Sending a malformed IKE_SA_INIT request leaved an incomplete state which caused a null pointer dereference if a subsequent CREATE_CHILD_SA request was sent. 2) Sending an IKE_AUTH request with either a missing TSi or TSr payload caused a null pointer derefence because the checks for TSi and TSr were interchanged. The IKEv2 fuzzer used was developped by the Orange Labs vulnerability research team. The tool was initially written by Gabriel Campana and is now maintained by Laurent Butti. * Added support for AES counter mode in ESP in IKEv2 using the proposal keywords aes128ctr, aes192ctr and aes256ctr. * Further progress in refactoring pluto: Use of the curl and ldap plugins for fetching crls and OCSP. Use of the random plugin to get keying material from /dev/random or /dev/urandom. Use of the openssl plugin as an alternative to the aes, des, sha1, sha2, and md5 plugins. The blowfish, twofish, and serpent encryption plugins are now optional and are not enabled by default. - Enabled new gcrypt plugin - Adopted spec file and modprobe to syslog patch - Removed obsolete getline glibc collision patch - Added patch to avoid library version for plugins (rpmlint). - Replaced update-dns-server patch with a --with-resolv-conf. - Removed restart_on_update from spec file (see bnc#450390). ------------------------------------------------------------------- Mon Jun 8 00:21:13 CEST 2009 - ro@suse.de - rename getline to my_getline to avoid collision with function from glibc ------------------------------------------------------------------- Tue Jun 2 09:56:16 CEST 2009 - mt@suse.de - Applied fix for a Denial-of-Service vulnerability where receiving a malformed IKE_SA_INIT request leaves an incomplete state which causes a crash of the IKEv2 charon while dereferencing a NULL pointer if a subsequent CREATE_CHILD_SA is received (bnc#507742). - Applied fix for a Denial-of-Service vulnerability where receiving a malformed IKE_AUTH request with either a missing TSi or TSr traffic selector payload causes a crash of the IKEv2 charon while dereferencing a NULL pointer because the NULL pointer checks of TSi and TSr before destruction were erroneously swapped (bnc#507742). ------------------------------------------------------------------- Tue Mar 31 11:19:03 CEST 2009 - mt@suse.de - Updated to strongSwan 4.2.14 release that fixes a grave DPD denial of service vulnerability registered as CVE-2009-0790, that had been slumbering in the code for many years: * A vulnerability in the Dead Peer Detection (RFC 3706) code was found by Gerd v. Egidy <gerd.von.egidy@intra2net.com> of Intra2net AG affecting all Openswan and strongSwan releases. A malicious (or expired ISAKMP) R_U_THERE or R_U_THERE_ACK Dead Peer Detection packet can cause the pluto IKE daemon to crash and restart. No authentication or encryption is required to trigger this bug. One spoofed UDP packet can cause the pluto IKE daemon to restart and be unresponsive for a few seconds while restarting. This DPD null state vulnerability has been officially registered as CVE-2009-0790 and is fixed by this release. * The new server-side EAP RADIUS plugin (--enable-eap-radius) relays EAP messages to and from a RADIUS server. Succesfully tested with with a freeradius server using EAP-MD5 and EAP-SIM. * ASN.1 to time_t conversion caused a time wrap-around for dates after Jan 18 03:14:07 UTC 2038 on 32-bit platforms. As a workaround such dates are set to the maximum representable time, i.e. Jan 19 03:14:07 UTC 2038. * Distinguished Names containing wildcards (*) are not sent in the IDr payload anymore. ------------------------------------------------------------------- Mon Oct 20 09:27:06 CEST 2008 - mt@suse.de - Updated to 4.2.8 release: * IKEv2 charon daemon supports authentication based on raw public keys stored in the SQL database backend. The ipsec listpubkeys command lists the available raw public keys via the stroke interface. * Several MOBIKE improvements: Detect changes in NAT mappings in DPD exchanges, handle events if kernel detects NAT mapping changes in UDP-encapsulated ESP packets (requires kernel patch), reuse old addesses in MOBIKE updates as long as possible and other fixes. * Fixed a bug in addr_in_subnet() which caused insertion of wrong source routes for destination subnets having netwmasks not being a multiple of 8 bits. Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. ------------------------------------------------------------------- Tue Oct 14 16:29:59 CEST 2008 - mt@suse.de - Applied fix for addr_in_subnet() extracted from strongswan-4.2.8 which caused insertion of wrong source routes for destination subnets having netwmasks not being a multiple of 8 bits. Thanks go to Wolfgang Steudel, TU Ilmenau for reporting this bug. (bnc#435200) ------------------------------------------------------------------- Fri Oct 10 08:08:35 CEST 2008 - mt@suse.de - Applied fix for a Denial-of-Service vulnerability where an IKE_SA_INIT message with a KE payload containing zeroes only can cause a crash of the IKEv2 charon daemon due to a NULL pointer returned by the mpz_export() function of the GNU Multi Precision (GMP) library. Thanks go to Mu Dynamics Research Labs for making us aware of this problem. (bnc#435194) ------------------------------------------------------------------- Thu Aug 28 14:31:49 CEST 2008 - mt@suse.de - Fixed to use --enable-curl instead of --enable-http as before - Enabled the OpenSSL crypto plugin in the spec file. ------------------------------------------------------------------- Thu Aug 28 09:48:14 CEST 2008 - mt@suse.de - Updated to 4.2.6 release, fixing bugs and offering a lot of new features comparing to the last version provided by this package. Most important are: * A NetworkManager plugin allows GUI-based configuration of road-warrior clients in a simple way. It features X509 based gateway authentication and EAP client authentication, tunnel setup/teardown and storing passwords in the Gnome Keyring. * A new EAP-GTC plugin implements draft-sheffer-ikev2-gtc-00.txt and allows username/password authentication against any PAM service on the gateway. The new EAP method interacts nicely with the NetworkManager plugin and allows client authentication against e.g. LDAP. * Improved support for the EAP-Identity method. The new ipsec.conf eap_identity parameter defines an additional identity to pass to the server in EAP authentication. * Fixed two multithreading deadlocks occurring when starting up several hundred tunnels concurrently. * Fixed the --enable-integrity-test configure option which computes a SHA-1 checksum over the libstrongswan library. * Consistent logging of IKE and CHILD SAs at the audit (AUD) level. * Improved the performance of the SQL-based virtual IP address pool by introducing an additional addresses table. The leases table storing only history information has become optional and can be disabled by setting charon.plugins.sql.lease_history = no in strongswan.conf. * The XFRM_STATE_AF_UNSPEC flag added to xfrm.h allows IPv4-over-IPv6 and IPv6-over-IPv4 tunnels with the 2.6.26 and later Linux kernels. * management of different virtual IP pools for different network interfaces have become possible. * fixed a bug which prevented the assignment of more than 256 virtual IP addresses from a pool managed by an sql database. * fixed a bug which did not delete own IPCOMP SAs in the kernel. * The openssl plugin supports the elliptic curve Diffie-Hellman groups 19, 20, 21, 25, and 26 and ECDSA authentication using elliptic curve X.509 certificates. * Fixed a bug in stroke which caused multiple charon threads to close the file descriptors during packet transfers over the stroke socket. * ESP sequence numbers are now migrated in IPsec SA updates handled by MOBIKE. Works only with Linux kernels >= 2.6.17. * Fixed a number of minor bugs that where discovered during the 4th IKEv2 interoperability workshop in San Antonio, TX. * Plugins for libstrongswan and charon can optionally be loaded according to a configuration in strongswan.conf. Most components provide a "load = " option followed by a space separated list of plugins to load. This allows e.g. the fallback from a hardware crypto accelerator to to software-based crypto plugins. * Charons SQL plugin has been extended by a virtual IP address pool. Configurations with a rightsourceip=%poolname setting query a SQLite or MySQL database for leases. The "ipsec pool" command helps in administrating the pool database. See ipsec pool --help for the available options * The Authenticated Encryption Algorithms AES-CCM-8/12/16 and AES-GCM-8/12/16 for ESP are now supported starting with the Linux 2.6.25 kernel. The syntax is e.g. esp=aes128ccm12 or esp=aes256gcm16. - Added patch disabling direct modifications of resolv.conf; has to be replaced by a netconfig call. - Added patch adding a missed file name argument in printf call in the scripts/thread_analysis.c file -- resulting binary is not installed. - Removed obsolete patches crash_badcfg_reload and old-caps-version. ------------------------------------------------------------------- Mon Jun 30 22:40:31 CEST 2008 - mt@suse.de - Added fix that explicitly enables version 1 linux capabilities on version 2 systems to aviod that the charon and pluto daemons exit because of failed capset call (bnc#404989). ------------------------------------------------------------------- Mon May 19 16:17:16 CEST 2008 - mt@suse.de - Applied fix (strongswan_crash_badcfg_reload.dif) to avoid a crash after reloading with bad config (bnc#392062). ------------------------------------------------------------------- Wed Apr 23 14:28:41 CEST 2008 - mt@suse.de - Updated to 4.2.1 release. A lot of code refactoring in the 4.2 release provides much more modularity and therefore much more extensiblity and offers the following new features: * libstrongswan has been modularized to attach crypto algorithms, credential implementations (secret and private keys, certificates) and http/ldap fetchers dynamically through plugins. * A relational database API that uses pluggable database providers was added to libstrongswan including plugins for MySQL and SQLite. * The IKEv2 keying charon daemon has become more extensible. Generic plugins can provide arbitrary interfaces to credential stores and connection management interfaces. Also any EAP method can be added. * The authentication and credential framework in charon has been heavily refactored to support modular credential providers, proper CERTREQ/CERT payload exchanges and extensible authorization rules. * Support for "Hash and URL" encoded certificate payloads has been implemented in the IKEv2 daemon charon. * The IKEv2 daemon charon now supports the "uniqueids" option to close multiple IKE_SAs with the same peer. * The crypto factory in libstrongswan additionally supports random number generators. Plugins may provide other sources of randomness. * Extended the credential framework by a caching option to allow plugins persistent caching of fetched credentials. * The new trust chain verification introduced in 4.2.0 has been parallelized. Threads fetching CRL or OCSP information no longer block other threads. * A new IKEv2 configuration attribute framework has been introduced allowing plugins to provide virtual IP addresses, and in the future, other configuration attribute services (e.g. DNS/WINS servers). * The stroke plugin has been extended to provide virtual IP addresses from a simple pool defined in ipsec.conf. * Fixed compilation on uClibc and a couple of other minor bugs. * The IKEv1 pluto daemon now supports the ESP encryption algorithm CAMELLIA with key lengths of 128, 192, and 256 bits, as well as the authentication algorithm AES_XCBC_MAC. - Applied a small patch defining _GNU_SOURCE for struct in6_pktinfo and adding inclusion of limits.h for PATH_MAX availability. - Added rpmlintrc file and a libtoolize call to the spec file. ------------------------------------------------------------------- Tue Feb 19 11:44:03 CET 2008 - mt@suse.de - Updated to 4.1.11 maintenance release, providing following fixes: * IKE rekeying in NAT situations did not inherit the NAT conditions to the rekeyed IKE_SA so that the UDP encapsulation was lost with the next CHILD_SA rekeying. * Wrong type definition of the next_payload variable in id_payload.c caused an INVALID_SYNTAX error on PowerPC platforms. * Implemented IKEv2 EAP-SIM server and client test modules that use triplets stored in a file. For details on the configuration see the scenario 'ikev2/rw-eap-sim-rsa'. - The 4.1.10 final version, declared upstream as "Fully tested support of IPv6 IPsec tunnel connections", fixes ordering error in oscp cache, IPv6 defaults of the nexthop parameter, adds support for new EAP modules [disabled in this build] and obsoletes our strongswan_path and strongswan_ipsec_script_msg patches. - Removed a sed call from init script. ------------------------------------------------------------------- Sat Dec 8 13:03:42 CET 2007 - mt@suse.de - Updated to 4.1.9 final, including all our patches. - Changed init script to use ipsec cmd using LSB codes now. - Added strongswan_path.dif setting a PATH in scripts (updown). - Added strongswan_ipsec_script_msg.dif for consistent look of ipsec script messages. - Added strongswan_modprobe_syslog.dif redirecting modprobe output to syslog. ------------------------------------------------------------------- Mon Nov 26 10:19:40 CET 2007 - mt@suse.de - Renamed charon plugins to avoid rpm conflicts with existing libraries (libstroke). Patch: strongswan-libconflicts.dif - Added init script. Template file: strongswan.init.in ------------------------------------------------------------------- Thu Nov 22 10:25:56 CET 2007 - mt@suse.de - Initial, unfinished package
