"The version of binutils installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2025-1181 advisory.

  - A vulnerability classified as critical was found in GNU Binutils 2.43. This vulnerability affects the
    function _bfd_elf_gc_mark_rsec of the file bfd/elflink.c of the component ld. The manipulation leads to
    memory corruption. The attack can be initiated remotely. The complexity of an attack is rather high. The
    exploitation appears to be difficult. The exploit has been disclosed to the public and May be used. The
    name of the patch is 931494c9a89558acb36a03a340c01726545eef24. It is recommended to apply a patch to fix
    this issue. (CVE-2025-1181)

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