Upgrade Debian:8 libav to version 6:11.12-1~deb8u6 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.
In FFmpeg 2.4 and 3.3.3, the read_data function in libavformat/hls.c does not restrict reload attempts for an insufficient list, which allows remote attackers to cause a denial of service (infinite loop).
