In FFmpeg 4.0.1, due to a missing check of a profile value before setting it, the ff_mpeg4_decode_picture_header function in libavcodec/mpeg4videodec.c may trigger a NULL pointer dereference while converting a crafted AVI file to MPEG4, leading to a denial of service.

Описание
In FFmpeg 3.2 and 4.1, a denial of service in the subtitle decoder allows attackers to hog the CPU via a crafted video file in Matroska format, because ff_htmlmarkup_to_ass in libavcodec/htmlsubtitles.c has a complex format argument to sscanf.
