- Update to 0.103.6
* CVE-2022-20770: Fixed a possible infinite loop vulnerability in the CHM
file parser. Issue affects versions 0.104.0 through 0.104.2 and LTS
version 0.103.5 and prior versions.
* CVE-2022-20796: Fixed a possible NULL-pointer dereference crash in the
scan verdict cache check. Issue affects versions 0.103.4, 0.103.5,
0.104.1, and 0.104.2.
* CVE-2022-20771: Fixed a possible infinite loop vulnerability in the
TIFF file parser. Issue affects versions 0.104.0 through 0.104.2 and
LTS version 0.103.5 and prior versions. The issue only occurs if the
"--alert-broken-media" ClamScan option is enabled. For ClamD, the
affected option is "AlertBrokenMedia yes", and for libclamav it is the
"CL_SCAN_HEURISTIC_BROKEN_MEDIA" scan option.
* CVE-2022-20785: Fixed a possible memory leak in the HTML file parser /
Javascript normalizer. Issue affects versions 0.104.0 through 0.104.2
and LTS version 0.103.5 and prior versions.
* CVE-2022-20792: Fixed a possible multi-byte heap buffer overflow write
vulnerability in the signature database load module. The fix was to
update the vendored regex library to the latest version. Issue affects
versions 0.104.0 through 0.104.2 and LTS version 0.103.5 and prior
versions.
* ClamOnAcc: Fixed a number of assorted stability issues and added
niceties for debugging ClamOnAcc.
* Fixed an issue causing byte-compare subsignatures to cause an alert
when they match even if other conditions of the given logical
signatures were not met.
* Fix memleak when using multiple byte-compare subsignatures. This fix
was backported from 0.104.0.
* Assorted bug fixes and improvements.
- Remove upstreamed clamav-ck_assert_msg.patch

- Update to 0.103.5
* CVE-2022-20698: Fix for invalid pointer read that may cause a crash.
This issue affects 0.104.1, 0.103.4 and prior when ClamAV is compiled
with libjson-c and the CL_SCAN_GENERAL_COLLECT_METADATA scan option
(the clamscan --gen-json option) is enabled.
* Fixed ability to disable the file size limit with libclamav C API,
like this:
cl_engine_set_num(engine, CL_ENGINE_MAX_FILESIZE, 0);
This issue didn't affect ClamD or ClamScan which also can disable the
limit by setting it to zero using MaxFileSize 0 in clamd.conf for ClamD,
or clamscan --max-filesize=0 for ClamScan.
Note: Internally, the max file size is still set to 2 GiB. Disabling the
limit for a scan will fall back on the internal 2 GiB limitation.
* Increased the maximum line length for ClamAV config files from 512 bytes
to 1,024 bytes to allow for longer config option strings.
* SigTool: Fix insufficient buffer size for --list-sigs that caused a
failure when listing a database containing one or more very long
signatures. This fix was backported from 0.104.

- Update to 0.103.4
* FreshClam:
- Add a 24-hour cool-down for FreshClam clients that have received
an HTTP 403 (Forbidden) response from the CDN. This is to reduce
the volume of 403-response data served to blocked FreshClam
clients that are configured with a tight update-loop.
- Fixed a bug where FreshClam treats an empty CDIFF as an
incremental update failure instead of as an intentional request
to download the whole CVD.
* ClamDScan: Fix a scan error when broken symlinks are encountered on
macOS with "FollowDirectorySymlinks" and "FollowFileSymlinks"
options disabled.
* Overhauled the scan recursion / nested archive extraction logic and
added new limits on embedded file-type recognition performed during
the "raw" scan of each file. This limits embedded file-type
misidentification and prevents detecting embedded file content that
is found/extracted and scanned at other layers in the scanning
process.
* Fix an issue with the FMap module that failed to read from some
nested files.
* Fixed an issue where failing to load some rules from a Yara file
containing multiple rules may cause a crash.
* Fixed assorted compiler warnings.
* Fixed assorted Coverity static code analysis issues.
* Scan limits:
- Added virus-name suffixes to the alerts that trigger when a scan
limit has been exceeded. Rather than simply
Heuristics.Limits.Exceeded, you may now see limit-specific
virus-names, to include:
+ Heuristics.Limits.Exceeded.MaxFileSize

- Update to 0.103.3
* Fixed a scan performance issue when ENGINE_OPTIONS_FORCE_TO_DISK is
enabled. This issue did not impacted most users but for those
affected it caused every scanned file to be copied to the temp
directory before the scan.
* Fix ClamDScan crashes when using the --fdpass --multiscan
command-line options in combination with the ClamD ExcludePath
config file options.
* Fixed an issue where the mirrors.dat file is owned by root when
starting as root (or with sudo) and using daemon-mode. File
ownership will be set to the DatabaseOwner just before FreshClam
switches to run as that user.
* Renamed the mirrors.dat file to freshclam.dat.
* Disabled the HTTPUserAgent config option if the DatabaseMirror uses
clamav.net. This will prevent users from being inadvertently blocked
and will ensure that we can keep better metrics on which ClamAV
versions are being used.
* Moved the detection for Heuristics.PNG.CVE-2010-1205 behind the
ClamScan --alert-broken-media option (ClamD AlertBrokenMedia yes)
option. This type of PNG issue appears to be common enough to be an
annoyance, and the CVE is old enough that no one should be
vulnerable at this point.
* Fix ClamSubmit failures after changes to Cloudflare "__cfduid"
cookies. See: https://blog.cloudflare.com/deprecating-cfduid-cookie/

- Update to 0.103.2
* CVE-2021-1386: Fix for UnRAR DLL load privilege escalation.
Affects 0.103.1 and prior on Windows only.
* CVE-2021-1252: Fix for Excel XLM parser infinite loop. Affects
0.103.0 and 0.103.1 only.
* CVE-2021-1404: Fix for PDF parser buffer over-read; possible
crash. Affects 0.103.0 and 0.103.1 only.
* CVE-2021-1405: Fix for mail parser NULL-dereference crash.
Affects 0.103.1 and prior.
* Fix possible memory leak in PNG parser.
* Fix ClamOnAcc scan on file-creation race condition so files are
scanned after their contents are written.
* FreshClam: Deprecate the SafeBrowsing config option. The
SafeBrowsing option will no longer do anything.
* For more details, see our blog post from last year about the
future of the ClamAV Safe Browsing database.
* FreshClam: Improved HTTP 304, 403, & 429 handling.
* FreshClam: Added back the mirrors.dat file to the database directory.
* FreshClam will now exit with a failure in daemon mode if an HTTP 403
(Forbidden) was received, because retrying later won't help any. The
FreshClam user will have to take actions to get unblocked.
* Fix the FreshClam mirror-sync issue where a downloaded database is
"older than the version advertised."

- Update to 0.103.1
* Added a new scan option to alert on broken media (graphics) file
formats. This feature mitigates the risk of malformed media files
intended to exploit vulnerabilities in other software. At present
media validation exists for JPEG, TIFF, PNG, and GIF files. To
enable this feature, set AlertBrokenMedia yes in clamd.conf, or
use the --alert-broken-media option when using clamscan. These
options are disabled by default in this patch release, but may be
enabled in a subsequent release. Application developers may enable
this scan option by enabling CL_SCAN_HEURISTIC_BROKEN_MEDIA for
the heuristic scan option bit field.
* Added CL_TYPE_TIFF, CL_TYPE_JPEG types to match GIF, PNG typing
behavior. BMP and JPEG 2000 files will continue to detect as
CL_TYPE_GRAPHICS because ClamAV does not yet have BMP or JPEG
2000 format checking capabilities.
* Fixed PNG parser logic bugs that caused an excess of parsing
errors and fixed a stack exhaustion issue affecting some systems
when scanning PNG files. PNG file type detection was disabled via
signature database update for ClamAV version 0.103.0 to mitigate
the effects from these bugs.
* Fixed an issue where PNG and GIF files no longer work with
Target:5 graphics signatures if detected as CL_TYPE_PNG/GIF rather
than as CL_TYPE_GRAPHICS. Target types now support up to 10
possible file types to make way for additional graphics types in
future releases.
* Fixed clamonacc's --fdpass option.
- Interprocess file descriptor passing for clamonacc was broken
since version 0.102.0 due to a bug introduced by the switch to
curl for communicating with clamd. On Linux, passing file
descriptors from one process to another is handled by the
kernel, so we reverted clamonacc to use standard system calls
for socket communication when fd passing is enabled.
* Fixed a clamonacc stack corruption issue on some systems when
using an older version of libcurl.
* Allow clamscan and clamdscan scans to proceed even if the
realpath lookup failed. This alleviates an issue on Windows
scanning files hosted on file- systems that do not support the
GetMappedFileNameW() API such as on ImDisk RAM-disks.
* Fixed freshclam --on-update-execute=EXIT_1 temporary directory
cleanup issue.
* clamd's log output and VirusEvent now provide the scan target's
file path instead of a file descriptor. The clamd socket API for
submitting a scan by FD-passing doesn't include a file path, this
feature works by looking up the file path by file descriptor.
This feature works on Mac and Linux but is not yet implemented
for other UNIX operating systems. FD-passing is not available for
Windows.
* Fixed an issue where freshclam database validation didn't work
correctly when run in daemon mode on Linux/Unix.
