CVE-2021-3566 Description

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).
