Descriptions

libavcodec/hevcdec.c in FFmpeg 3.4 and 4.1.2 mishandles detection of duplicate first slices, which allows remote attackers to cause a denial of service (NULL pointer dereference and out-of-array access) or possibly have unspecified other impact via crafted HEVC data.

libavcodec/hevcdec.c en FFmpeg versión 3.4 y versión 4.1.2 maneja de forma incorrecta la detección de los primeros cortes duplicados, lo que permite a los atacantes remotos causar una denegación de servicio (desreferencia de puntero NULL y acceso fuera de límites) o posiblemente tener otro impacto no especificado a través de datos HEVC diseñados.
