"The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the
ELSA-2024-2302 advisory.

  - GStreamer PGS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This
    vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer.
    Interaction with this library is required to exploit this vulnerability but attack vectors may vary
    depending on the implementation. The specific flaw exists within the parsing of PGS subtitle files. The
    issue results from the lack of proper validation of the length of user-supplied data prior to copying it
    to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the
    current process. Was ZDI-CAN-20994. (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.");
