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). Anterior a versión 4.3 de ffmpeg, el demuxer tty no tenía una función "read_probe" asignada. Si se diseña un archivo "ffconcat" legítimo que haga referencia a una imagen, seguido de un archivo que desencadenar el demuxer tty, el contenido del segundo archivo se copiará en el archivo de salida literalmente (siempre que se pase la opción "vcodec copy" a ffmpeg) • https://github.com/FFmpeg/FFmpeg/commit/3bce9e9b3ea35c54bacccc793d7da99ea5157532#diff-74f6b92a0541378ad15de9c29c0a2b0c69881ad9ffc71abe568b88b535e00a7f https://lists.debian.org/debian-lts-announce/2021/08/msg00018.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

FFmpeg 2.8 and 4.2.3 has a use-after-free via a crafted EXTINF duration in an m3u8 file because parse_playlist in libavformat/hls.c frees a pointer, and later that pointer is accessed in av_probe_input_format3 in libavformat/format.c. FFmpeg versión 2.8 y versión 4.2.3, presenta un uso de la memoria previamente liberada por medio de una duración EXTINF diseñada en un archivo m3u8 porque la función parse_playlist en la biblioteca libavformat/hls.c libera un puntero, y luego este puntero es accedido en la función av_probe_input_format3 en la biblioteca libavformat/format.c • https://github.com/FFmpeg/FFmpeg/commit/6959358683c7533f586c07a766acc5fe9544d8b2 https://lists.debian.org/debian-lts-announce/2020/07/msg00022.html https://patchwork.ffmpeg.org/project/ffmpeg/patch/20200529033905.41926-1-lq%40chinaffmpeg.org https://security.gentoo.org/glsa/202007-58 https://trac.ffmpeg.org/ticket/8673 https://usn.ubuntu.com/4431-1 https://www.debian.org/security/2020/dsa-4722 • CWE-416: Use After Free •
