"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-2025-1352 advisory.

  - A vulnerability has been found in GNU elfutils 0.192 and classified as critical. This vulnerability
    affects the function __libdw_thread_tail in the library libdw_alloc.c of the component eu-readelf. The
    manipulation of the argument w 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
    2636426a091bd6c6f7f02e49ab20d4cdc6bfc753. It is recommended to apply a patch to fix this issue.
    (CVE-2025-1352)

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