CVE-2026-3085

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.

Summary
  • (es) Vulnerabilidad de ejecución remota de código por desbordamiento de búfer basado en montículo en GStreamer rtpqdm2depay. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de GStreamer. La interacción con esta biblioteca es necesaria para explotar esta vulnerabilidad, pero los vectores de ataque pueden variar dependiendo de la implementación. La falla específica existe en el procesamiento de cargas útiles RTP X-QDM. El problema resulta de la falta de validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos a un búfer basado en montículo. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Fue ZDI-CAN-28851.
