CVE-2026-3083

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.

Summary
  • (es) Vulnerabilidad de ejecución remota de código por escritura fuera de límites en GStreamer rtpqdm2depay. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de GStreamer. Se requiere interacción con esta biblioteca para explotar esta vulnerabilidad, pero los vectores de ataque pueden variar dependiendo de la implementación. La falla específica existe en el procesamiento de los elementos de carga útil RTP X-QDM. Al analizar el elemento 'packetid', el proceso no valida correctamente los datos proporcionados por el usuario, lo que puede resultar en una escritura más allá del final de un array asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Fue ZDI-CAN-28850.
