Descriptions
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
