CVE-2013-0894

Estado: ModificadaAlta (7.5)—

Desbordamiento de búfer en la función vorbis_parse_setup_hdr_floors en el decodificador Vorbis en vorbisdec.c en libavcodec de FFmpeg en a v1.1.3, tal como se utiliza en Google Chrome antes v25.0.1364.97 en Windows y Linux, y antes v25.0.1364.99 en Mac OS X y otros productos, permite atacantes remotos provocar una denegación de servicio (división por cero error o fuera de límites de acceso a matriz) o posiblemente tener un impacto no especificado a través de vectores relacionados con un valor de cero para un tamaño de mapa corteza.
