"The version of elfutils installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2025-1377 advisory.

  - A vulnerability, which was classified as problematic, has been found in GNU elfutils 0.192. This issue
    affects the function gelf_getsymshndx of the file strip.c of the component eu-strip. The manipulation
    leads to denial of service. The attack needs to be approached locally. The exploit has been disclosed to
    the public and May be used. The identifier of the patch is fbf1df9ca286de3323ae541973b08449f8d03aba. It is
    recommended to apply a patch to fix this issue. (CVE-2025-1377)

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