"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-2025-1372 advisory.

  - A vulnerability was found in GNU elfutils 0.192. It has been declared as critical. Affected by this
    vulnerability is the function dump_data_section/print_string_section of the file readelf.c of the
    component eu-readelf. The manipulation of the argument z/x leads to buffer overflow. An attack has to be
    approached locally. The exploit has been disclosed to the public and May be used. The identifier of the
    patch is 73db9d2021cab9e23fd734b0a76a612d52a6f1db. It is recommended to apply a patch to fix this issue.
    (CVE-2025-1372)

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