CVE-2022-27148

MP4 parsing crash via signed integer overflow

Published Apr 8, 2022 · Updated Aug 3, 2024

Integer overflow in MP4Box 1.1.0-DEV-rev1663-g881c6a94a-master allows attackers to cause a service crash via a crafted MP4 file. The parser in media_tools/av_parsers.c multiplies an attacker-controlled integer by 16 in a signed int, triggering undefined-behavior sanitizer termination. Reaching the impact requires processing the malicious file with MP4Box; evidence demonstrates denial of service, with no demonstrated confidentiality or integrity compromise.
