CVE-2015-8661 (opens in a new tab)How to fix?
Upgrade Debian:8 libav to version 6:11.12-1~deb8u2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libav package and not the libav package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
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.
