"The version of gstreamer-plugins-base installed on the remote host is prior to 0.10.36-18. It is, therefore, affected by
a vulnerability as referenced in the ALAS2-2024-2593 advisory.

    GStreamer EXIF Metadata Parsing Integer 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 EXIF metadata. The issue results from the lack of proper
    validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An
    attacker can leverage this vulnerability to execute code in the context of the current process.. Was ZDI-
    CAN-23896. (CVE-2024-4453)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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