CVE-2014-125023Network attack vector

Service interruption via unchecked TrueMotion1 header length

Published Jun 19, 2022 · Updated Apr 15, 2025

Memory corruption in FFmpeg 2.0's TrueMotion1 decoder allows remote attackers to interrupt media processing with crafted video data. truemotion1_decode_header uses the packet-declared header length to XOR input bytes without first ensuring that the packet contains the full declared header. No authentication is required; reaching a process that decodes the malformed stream can terminate that process, with no published confidentiality or integrity impact.
