GStreamer rtpqdm2depay Heap-based Buffer Overflow Remote Code Execution Vulnerability

Published Mar 13, 2026

Description

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.

Affected products

Remediation

Red Hat statement

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.

Red Hat mitigation

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.
