The update_dimensions function in libavcodec/vp8.c in FFmpeg through 2.8.1,
as used in Google Chrome before 46.0.2490.71 and other products, relies on
a coefficient-partition count during multi-threaded operation, which allows
remote attackers to cause a denial of service (race condition and memory
corruption) or possibly have unspecified other impact via a crafted WebM
file.
