CVE-2021-3566  (opens in a new tab)

How to fix?

There is no fixed version for Ubuntu:18.04 ffmpeg.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ffmpeg package and not the ffmpeg package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 relevant fixed versions and status.

Prior to ffmpeg version 4.3, the tty demuxer did not have a 'read_probe' function assigned to it. By crafting a legitimate "ffconcat" file that references an image, followed by a file the triggers the tty demuxer, the contents of the second file will be copied into the output file verbatim (as long as the -vcodec copy option is passed to ffmpeg).
