Details

FFmpeg is a complete and free Internet live audio and video broadcasting solution for Linux/Unix. It also includes a digital VCR. It can encode in real time in many formats including MPEG1 audio and video, MPEG4, h263, ac3, asf, avi, real, mjpeg, and flash.

Security Fix(es):

A flaw was found in FFmpeg s TTY Demuxer. This vulnerability allows possible data exfiltration via improper parsing of non-TTY-compliant input files in HLS playlists.(CVE-2023-6602)

An out-of-bounds write vulnerability in FFmpeg's libavcodec library, specifically in the MagicYUV decoder, allows denial-of-service and, in some cases, can be exploited for remote code execution.

This vulnerability is associated with the file libavcodec/magicyuv.C.

This issue affects FFmpeg before version 8.1.2.(CVE-2026-8461)
