Description
A heap-based buffer overflow vulnerability exists in the GStreamer rtpqdm2depay plugin affecting multiple versions prior to fixed releases. This flaw allows remote attackers to execute arbitrary code by sending specially crafted X-QDM RTP payloads that bypass length validation before copying data to a heap buffer. The vulnerability has a high severity with a CVSS score of 8.8 and impacts confidentiality, integrity, and availability. Fixed versions are available and patches have been released by Ubuntu.
