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.

A flaw was found in GStreamer. This heap-based buffer overflow vulnerability in the rtpqdm2depay component allows a remote attacker to execute arbitrary code. The flaw occurs due to insufficient validation of user-supplied data length during the processing of X-QDM Real-time Transport Protocol (RTP) payloads. Successful exploitation can lead to remote code execution within the context of the current process.

This is an IMPORTANT vulnerability in the GStreamer rtpqdm2depay plugin. The flaw enables remote code execution through a heap-based buffer overflow when processing specially crafted X-QDM RTP payloads. Exploitation requires an application to interact with the vulnerable GStreamer library to process such untrusted media streams. To mitigate this issue, avoid processing X-QDM RTP payloads from untrusted sources. Restricting network access to applications that utilize GStreamer for RTP stream processing can limit exposure.
