UBUNTU-CVE-2026-3085: Buffer Overflow
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.

Frequently Asked Questions
What must an attacker do to exploit this issue?
An attacker must cause the affected GStreamer installation to process a malicious X-QDM RTP payload. User interaction with the library is required, and the precise delivery path depends on how the application implements GStreamer.
What is the likely impact if exploitation succeeds?
Successful exploitation can allow remote code execution in the context of the current process. The reported impact includes high confidentiality, integrity, and availability consequences.
Which component should Ubuntu users check?
Check whether the Ubuntu gst-plugins-good1.0 package is installed or used by applications that process RTP streams, particularly X-QDM RTP payloads.
