"The version of atril installed on the remote host is prior to 1.20.2-1. It is, therefore, affected by a vulnerability as
referenced in the ALAS2MATE-DESKTOP1.X-2024-006 advisory.

  - Atril Document Viewer is the default document reader of the MATE desktop environment for Linux. A path
    traversal and arbitrary file write vulnerability exists in versions of Atril prior to 1.26.2. This
    vulnerability is capable of writing arbitrary files anywhere on the filesystem to which the user opening a
    crafted document has access. The only limitation is that this vulnerability cannot be exploited to
    overwrite existing files, but that doesn't stop an attacker from achieving Remote Command Execution on the
    target system. Version 1.26.2 of Atril contains a patch for this vulnerability. (CVE-2023-52076)

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