Descriptions

Heap-based buffer overflow in the vqa_decode_chunk function in the VQA codec (vqavideo.c) in libavcodec in Libav 0.5.x before 0.5.9, 0.6.x before 0.6.6, 0.7.x before 0.7.6, and 0.8.x before 0.8.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VQA media file in which the image size is not a multiple of the block size.

Un desbordamiento de búfer basado en memoria dinámica ('heap') en la función vqa_decode_chunk en el códec VQA (vqavideo.c) en libavcodec en Libav v0.5.x antes de v0.5.9, v0.6.x antes de v0.6.6, v0.7.x antes de v0.7.6 y v0.8.x antes de v0.8.2 permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) y posiblemente ejecutar código de su elección a través de un archivo multimedia VQA modificado en el que el tamaño de la imagen no es múltiplo del tamaño del bloque.

Multiple vulnerabilities were found in FFmpeg, the worst of which might enable remote attackers to cause user-assisted execution of arbitrary code. Versions less than 1.0.7 are affected.
