GStreamer rtpqdm2depay 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 processing of X-QDM RTP payloads. 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-28851.

Detection & IOCsextracted from sources · hover to see the quote

  • Target the GStreamer rtpqdm2depay plugin component — heap-based buffer overflow is triggered during processing of X-QDM RTP payloads with insufficient length validation before copying user-supplied data to a heap buffer.
  • Monitor network traffic and application logs for GStreamer processing X-QDM RTP (Real-time Transport Protocol) payloads from untrusted/external sources, as this is the specific attack vector.
  • Alert on applications loading or invoking the GStreamer rtpqdm2depay plugin (gst-plugins-good) when receiving RTP streams from untrusted network sources, as exploitation requires interaction with this library.
  • ·Exploitation requires an application to actively process X-QDM RTP payloads via GStreamer; attack surface varies by implementation and deployment context.
  • ·Mitigation (short of patching) is to avoid processing X-QDM RTP payloads from untrusted sources and restrict network access to GStreamer-based RTP stream processing applications.
  • ·Debian scope is listed as 'local' in the security tracker, which may affect network-based detection assumptions depending on the deployment environment.
