gcc-toolset-13-binutils-2.40-8.el9 build changelog.

  - GNU binutils gold gold v1.11-v1.16 (GNU binutils v2.21-v2.31.1) is affected by: Improper Input Validation,
    Signed/Unsigned Comparison, Out-of-bounds Read. The impact is: Denial of service. The component is:
    gold/fileread.cc:497, elfcpp/elfcpp_file.h:644. The attack vector is: An ELF file with an invalid e_shoff
    header field must be opened. (CVE-2019-1010204)

  - There is an open race window when writing output in the following utilities in GNU binutils version 2.35
    and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as
    part of a script updating binaries across different users), an unprivileged user can trick these utilities
    into getting ownership of arbitrary files through a symlink. (CVE-2021-20197)

  - A flaw was discovered in GNU libiberty within demangle_path() in rust-demangle.c, as distributed in GNU
    Binutils version 2.36. A crafted symbol can cause stack memory to be exhausted leading to a crash.
    (CVE-2021-3530)

  - An illegal memory access flaw was found in the binutils package. Parsing an ELF file containing corrupt
    symbol version information may result in a denial of service. This issue is the result of an incomplete
    fix for CVE-2020-16599. (CVE-2022-4285)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
