The remote CentOS Linux 8 host has packages installed that are affected by a vulnerability as referenced in the CESA-2024:3089 advisory.

  • GStreamer FLAC 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 FLAC audio 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-20775. (CVE-2023-37327)

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