Description Victor Pereira 2015-12-30 08:10:39 UTC

The h264_slice_header_init function in libavcodec/h264_slice.c in FFmpeg before
2.8.3 does not validate the relationship between the number of threads and the
number of slices, which allows remote attackers to cause a denial of service
(out-of-bounds array access) or possibly have unspecified other impact via
crafted H.264 data.
