CVE-2017-15672 (opens in a new tab)How to fix?
Upgrade Debian:8 libav to version 6:11.12-1~deb8u4 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 read_header function in libavcodec/ffv1dec.c in FFmpeg 2.4 and 3.3.4 and possibly earlier allows remote attackers to have unspecified impact via a crafted MP4 file, which triggers an out-of-bounds read.
