CVE-2017-14056 (opens in a new tab)How to fix?
Upgrade Debian:10 ffmpeg to version 7:3.3.4-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ffmpeg package and not the ffmpeg package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
In libavformat/rl2.c in FFmpeg 3.3.3, a DoS in rl2_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. When a crafted RL2 file, which claims a large "frame_count" field in the header but does not contain sufficient backing data, is provided, the loops (for offset and size tables) would consume huge CPU and memory resources, since there is no EOF check inside these loops.
