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. NOTE: Third parties dispute that this is a vulnerability because “no evidence of a vulnerability is provided” and only “a generic warning from a static code analysis” is provided

** EN DISPUTA ** Un desbordamiento de búfer basado en pila en el decodificador de subtítulos en Libav 12.3 permite a los atacantes corromper la pila a través de un archivo de video especialmente diseñado en formato Matroska, porque srt_to_ass en libavcodec / srtdec.c usa mal snprintf. NOTA: Los terceros discuten que esto es una vulnerabilidad porque "no se proporciona evidencia de una vulnerabilidad" y solo se proporciona "una advertencia genérica de un análisis de código estático".
