The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:4364 advisory.

    The binutils packages provide a collection of binary utilities for the manipulation of object code in     various object file formats. It includes the ar, as, gprof, ld, nm, objcopy, objdump, ranlib, readelf,     size, strings, strip, and addr2line utilities.

    Security Fix(es):

    * binutils: Excessive debug section size can cause excessive memory consumption in bfd's dwarf2.c     read_section() (CVE-2021-3487)

    * binutils: Race window allows users to own arbitrary files (CVE-2021-20197)

    * binutils: Heap-based buffer overflow in bfd_getl_signed_32() in libbfd.c because sh_entsize is not     validated in _bfd_elf_slurp_secondary_reloc_section() in elf.c (CVE-2020-35448)

    * binutils: Heap-based buffer overflow in _bfd_elf_slurp_secondary_reloc_section in elf.c (CVE-2021-20284)

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

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the 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.

The remote host is affected by the vulnerability described in GLSA-202208-30 (GNU Binutils: Multiple Vulnerabilities)

  - 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 found in GNU Binutils 2.35.1, where there is a heap-based buffer overflow in
    _bfd_elf_slurp_secondary_reloc_section in elf.c due to the number of symbols not calculated correctly. The     highest threat from this vulnerability is to system availability. (CVE-2021-20284)

  - A flaw was found in binutils readelf 2.35 program. An attacker who is able to convince a victim using     readelf to read a crafted file could trigger a stack buffer overflow, out-of-bounds write of arbitrary     data supplied by the attacker. The highest impact of this flaw is to confidentiality, integrity, and     availability. (CVE-2021-20294)

  - There's a flaw in the BFD library of binutils in versions before 2.36. An attacker who supplies a crafted     file to an application linked with BFD, and using the DWARF functionality, could cause an impact to system     availability by way of excessive memory consumption. (CVE-2021-3487)

  - 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 out of bounds flaw was found in GNU binutils objdump utility version 2.36. An attacker could use this     flaw and pass a large section to avr_elf32_load_records_from_section() probably resulting in a crash or in     some cases memory corruption. The highest threat from this vulnerability is to integrity as well as system     availability. (CVE-2021-3549)

  - stab_xcoff_builtin_type in stabs.c in GNU Binutils through 2.37 allows attackers to cause a denial of     service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-     of-bounds write. NOTE: this issue exists because of an incorrect fix for CVE-2018-12699. (CVE-2021-45078)

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