Astra Linux - уязвимость в ffmpeg

Before ffmpeg version 4.3, the tty demuxer did not have a ‘readprobe’ function assigned to it. By creating a legitimate “ffconcat” file that references an image, followed by a file that triggers the tty demuxer, the contents of the second file will be copied into the output file verbatim as long ...
