The version of gstreamer1-plugins-base installed on the remote host is prior to 1.18.4-5. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2120 advisory.

  • Heap overwrite in subtitle parsing (CVE-2023-37328) (CVE-2023-37328)

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