  <summary>Security update for binutils</summary>
  <description>This update for binutils fixes the following issues:

Update to binutils 2.37:

* The GNU Binutils sources now requires a C99 compiler and library to
  build.
* Support for Realm Management Extension (RME) for AArch64 has been
  added.
* A new linker option '-z report-relative-reloc' for x86 ELF targets
  has been added to report dynamic relative relocations.
* A new linker option '-z start-stop-gc' has been added to disable
  special treatment of __start_*/__stop_* references when
  --gc-sections.
* A new linker options '-Bno-symbolic' has been added which will
  cancel the '-Bsymbolic' and '-Bsymbolic-functions' options.
* The readelf tool has a new command line option which can be used to
  specify how the numeric values of symbols are reported.
  --sym-base=0|8|10|16 tells readelf to display the values in base 8,
  base 10 or base 16.  A sym base of 0 represents the default action
  of displaying values under 10000 in base 10 and values above that in
  base 16.
* A new format has been added to the nm program.  Specifying
  '--format=just-symbols' (or just using -j) will tell the program to
  only display symbol names and nothing else.
* A new command line option '--keep-section-symbols' has been added to
  objcopy and strip.  This stops the removal of unused section symbols
  when the file is copied.  Removing these symbols saves space, but
  sometimes they are needed by other tools.
* The '--weaken', '--weaken-symbol' and '--weaken-symbols' options
  supported by objcopy now make undefined symbols weak on targets that
  support weak symbols. 
* Readelf and objdump can now display and use the contents of .debug_sup
  sections.
* Readelf and objdump will now follow links to separate debug info
  files by default.  This behaviour can be stopped via the use of the
  new '-wN' or '--debug-dump=no-follow-links' options for readelf and
  the '-WN' or '--dwarf=no-follow-links' options for objdump.  Also
  the old behaviour can be restored by the use of the
  '--enable-follow-debug-links=no' configure time option.

The semantics of the =follow-links option have also been slightly
  changed.  When enabled, the option allows for the loading of symbol
  tables and string tables from the separate files which can be used
  to enhance the information displayed when dumping other sections,
  but it does not automatically imply that information from the
  separate files should be displayed.

If other debug section display options are also enabled (eg
  '--debug-dump=info') then the contents of matching sections in both
  the main file and the separate debuginfo file *will* be displayed.
  This is because in most cases the debug section will only be present
  in one of the files.

If however non-debug section display options are enabled (eg
  '--sections') then the contents of matching parts of the separate
  debuginfo file will *not* be displayed.  This is because in most
  cases the user probably only wanted to load the symbol information
  from the separate debuginfo file.  In order to change this behaviour
  a new command line option --process-links can be used.  This will
  allow di0pslay options to applied to both the main file and any
  separate debuginfo files.

* Nm has a new command line option: '--quiet'.  This suppresses "no
  symbols" diagnostic.

Update to binutils 2.36:

New features in the Assembler:

- General:

* When setting the link order attribute of ELF sections, it is now
     possible to use a numeric section index instead of symbol name.
   * Added a .nop directive to generate a single no-op instruction in
     a target neutral manner.  This instruction does have an effect on
     DWARF line number generation, if that is active.
   * Removed --reduce-memory-overheads and --hash-size as gas now
     uses hash tables that can be expand and shrink automatically.

- X86/x86_64:

* Add support for AVX VNNI, HRESET, UINTR, TDX, AMX and Key
     Locker instructions. 
   * Support non-absolute segment values for lcall and ljmp.
   * Add {disp16} pseudo prefix to x86 assembler.
   * Configure with --enable-x86-used-note by default for Linux/x86.

-  ARM/AArch64:

* Add support for Cortex-A78, Cortex-A78AE and Cortex-X1,
     Cortex-R82, Neoverse V1, and Neoverse N2 cores.
   * Add support for ETMv4 (Embedded Trace Macrocell), ETE (Embedded
     Trace Extension), TRBE (Trace Buffer Extension), CSRE (Call
     Stack Recorder Extension) and BRBE (Branch Record Buffer
     Extension) system registers.
   * Add support for Armv8-R and Armv8.7-A ISA extensions.
   * Add support for DSB memory nXS barrier, WFET and WFIT
     instruction for Armv8.7.
   * Add support for +csre feature for -march. Add CSR PDEC
     instruction for CSRE feature in AArch64.
   * Add support for +flagm feature for -march in Armv8.4 AArch64.
   * Add support for +ls64 feature for -march in Armv8.7
     AArch64. Add atomic 64-byte load/store instructions for this
     feature. 
   * Add support for +pauth (Pointer Authentication) feature for
     -march in AArch64.

New features in the Linker:

* Add --error-handling-script=&lt;NAME> command line option to allow
    a helper script to be invoked when an undefined symbol or a
    missing library is encountered.  This option can be suppressed
    via the configure time switch: --enable-error-handling-script=no.
  * Add -z x86-64-{baseline|v[234]} to the x86 ELF linker to mark
    x86-64-{baseline|v[234]} ISA level as needed.
  * Add -z unique-symbol to avoid duplicated local symbol names.
  * The creation of PE format DLLs now defaults to using a more
    secure set of DLL characteristics.
  * The linker now deduplicates the types in .ctf sections.  The new 
     command-line option --ctf-share-types describes how to do this:
     its default value, share-unconflicted, produces the most compact
     output.
  * The linker now omits the "variable section" from .ctf sections
    by default, saving space.  This is almost certainly what you
    want unless you are working on a project that has its own
    analogue of symbol tables that are not reflected in the ELF
    symtabs.

New features in other binary tools:

* The ar tool's previously unused l modifier is now used for
    specifying dependencies of a static library. The arguments of
    this option (or --record-libdeps long form option) will be
    stored verbatim in the __.LIBDEP member of the archive, which
    the linker may read at link time.
  * Readelf can now display the contents of LTO symbol table
    sections when asked to do so via the --lto-syms command line
    option.
  * Readelf now accepts the -C command line option to enable the
    demangling of symbol names.  In addition the --demangle=&lt;style>,
    --no-demangle, --recurse-limit and --no-recurse-limit options
    are also now availale.

The following security fixes are addressed by the update:

- CVE-2021-20197: Fixed a race condition which allows users to own arbitrary files (bsc#1181452).
- CVE-2021-20284: Fixed a heap-based buffer overflow in _bfd_elf_slurp_secondary_reloc_section in elf.c (bsc#1183511).

- CVE-2020-16590: Fixed a double free vulnerability in process_symbol_table() (bsc#1179898).
- CVE-2020-16591: Fixed an invalid read in process_symbol_table() (bsc#1179899).
- CVE-2020-16592: Fixed an use-after-free in bfd_hash_lookup() (bsc#1179900).

- CVE-2020-16598: Fixed a null pointer dereference in debug_get_real_type() (bsc#1179902).
- CVE-2020-16599: Fixed a null pointer dereference in _bfd_elf_get_symbol_version_string() (bsc#1179903)
- CVE-2020-35493: Fixed heap-based buffer overflow in bfd_pef_parse_function_stubs function in bfd/pef.c via crafted PEF file (bsc#1180451).
- CVE-2020-35496: Fixed multiple null pointer dereferences in bfd module due to not checking return value of bfd_malloc (bsc#1180454).
