Medium [CVE-2026-65704] Heap corruption via crafted ffconcat file can lead to arbitrary code execution
CVE-2026-65704Source published Source updated
FFmpeg through 8.1.2 contains an out-of-bounds write vulnerability that allows attackers to cause heap corruption by supplying a crafted ffconcat file processed with the -safe 0 flag. The TY demuxer's demux_audio() function decrements packet size without bounds checking, producing a negative size value that is passed to memcpy() in shorten_decode_frame(), where conversion to size_t wraps the value to near SIZE_MAX and triggers reads beyond the source allocation and writes far beyond the Shorten decoder's bitstream buffer. A flaw was found in FFmpeg. This occurs due to improper bounds checking in the TY demuxer's demux_audio() function, leading to heap corruption. Successful exploitation can result in arbitrary code execution, allowing the attacker to take control of the affected system.…
