Descriptions

Integer overflow in the vmnc decoder in the gstreamer allows remote attackers to cause a denial of service (crash) via large width and height values, which triggers a buffer overflow.

Desbordamiento de entero en el decodificador vmnc en el gstreamer permite a atacantes remotos provocar una denegación de servicio (caída) a través de valores de anchura y altura grandes, lo que desencadena un desbordamiento de búfer.

An integer overflow flaw, leading to a heap-based buffer overflow, was found in GStreamer's VMware VMnc video file format decoding plug-in. A remote attacker could use this flaw to cause an application using GStreamer to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
