"The version of binutils / gdb 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-2025-1182 advisory.

  - A vulnerability, which was classified as critical, was found in GNU Binutils 2.43. Affected is the
    function bfd_elf_reloc_symbol_deleted_p of the file bfd/elflink.c of the component ld. The manipulation
    leads to memory corruption. It is possible to launch the attack remotely. The complexity of an attack is
    rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and
    May be used. The patch is identified as b425859021d17adf62f06fb904797cf8642986ad. It is recommended to
    apply a patch to fix this issue. (CVE-2025-1182)

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