Descriptions

GStreamer AV1 Codec Parsing 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 parsing of AV1 encoded video files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22226.

Vulnerabilidad de ejecución remota de código de desbordamiento de búfer de almacenamiento dinámico de análisis de GStreamer AV1 Codec. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de GStreamer. Se requiere la interacción con esta librería para aprovechar esta vulnerabilidad, pero los vectores de ataque pueden variar según la implementación. La falla específica existe en el análisis de archivos de video codificados con AV1. El problema se debe a la falta de una validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer basado en montón de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Era ZDI-CAN-22226.

A heap-based buffer overflow vulnerability was found in GStreamer in the AV1 codec parser when handling certain malformed streams. A malicious third party could use this flaw to trigger a crash in the application and possibly affect code execution through heap manipulation.
