Description
GStreamer rtpqdm2depay Out-Of-Bounds Write 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 payload elements. When parsing the packetid element, the process does not properly validate user-supplied data, which can result in a write past the end of an allocated array. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28850.
Analysis
Critical out-of-bounds write vulnerability in GStreamer's rtpqdm2depay component that allows remote code execution when processing malformed X-QDM RTP payloads. The vulnerability affects all versions of GStreamer (CPE shows wildcard versioning) and requires user interaction, though attack vectors vary by implementation. …

Remediation
Within 24 hours: Identify and inventory all systems running GStreamer, particularly those exposed to untrusted RTP streams or user-controlled media inputs; assess which applications are critical to business operations. Within 7 days: Implement network segmentation to restrict RTP traffic to trusted sources only, disable rtpqdm2depay component where feasible, and apply input validation/filtering at network boundaries. …
