CVE-2023-40474

Vulnerabilidad de ejecución remota de código de desbordamiento de enteros en el análisis de archivos MXF de GStreamer. 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 MXF. El problema se debe a la falta de validación adecuada de los datos proporcionados por el usuario, lo que puede provocar un desbordamiento de enteros antes de asignar un búfer. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Era ZDI-CAN-21660.

GStreamer MXF File Parsing Integer 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 MXF video files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
. Was ZDI-CAN-21660.

A heap-buffer overflow flaw was found in the MXF file demuxer in the GStreamer Plugins Bad when handling malformed files with an uncompressed video. This issue requires user interaction with the library, and could allow a malicious user to cause an integer overflow before allocating the buffer, triggering a crash or code execution via heap manipulation, executing code in the context of the current process.
