"The remote NewStart CGSL host, running version MAIN 7.02, has binutils packages installed that are affected by a
vulnerability:

  - A vulnerability, which was classified as problematic, was found in GNU Binutils up to 2.43. This affects
    the function disassemble_bytes of the file binutils/objdump.c. The manipulation of the argument buf leads
    to stack-based buffer overflow. It is possible to initiate 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. Upgrading to version 2.44 is able to address this issue. The identifier of the
    patch is baac6c221e9d69335bf41366a1c7d87d8ab2f893. It is recommended to upgrade the affected component.
    (CVE-2025-0840)

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