Descriptions
A stack-based buffer overflow in the subtitle decoder in Libav 12.3 allows attackers to corrupt the stack via a crafted video file in Matroska format, because srt_to_ass in libavcodec/srtdec.c misuses snprintf.
Un desbordamiento del búfer en la región stack de la memoria en el decodificador de subtítulos en Libav versión 12.3, permite a atacantes corromper la pila por medio de un archivo de video diseñado en formato Matroska, porque la función srt_to_ass en el archivo libavcodec/srtdec.c utiliza inapropiadamente snprintf.
