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.

Executive Summary

CVE-2026-3085 is a heap-based buffer overflow vulnerability in the GStreamer library, specifically in the rtpqdm2depay element that processes X-QDM RTP payloads.

The flaw occurs because the length of user-supplied data is not properly validated before it is copied into a heap buffer.

This allows remote attackers to execute arbitrary code within the context of the affected process.

Exploitation requires interaction with the GStreamer library, but the exact attack vectors may vary depending on how the library is implemented.

Impact Analysis

This vulnerability can have severe impacts including remote code execution by attackers.

An attacker can run arbitrary code in the context of the affected process, potentially leading to full compromise of the system running GStreamer.

The CVSS score of 8.8 indicates high severity with significant impacts on confidentiality, integrity, and availability.
