"The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
CESA-2024:3060 advisory.

  - GStreamer MXF File 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 MXF video files. 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-21660. (CVE-2023-40474)

    process. Was ZDI-CAN-21661. (CVE-2023-40475)

  - GStreamer H265 Parsing Stack-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 H265 encoded video files. The issue results
    from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-
    length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of
    the current process. Was ZDI-CAN-21768. (CVE-2023-40476)
