CVE-2022-3814Public exploitNetwork attack vector

Process memory exhaustion via unreleased parsed atoms

Published Nov 1, 2022 · Updated Apr 15, 2025

Memory leak in Axiomatic Systems Bento4 mp4decrypt allows remote attackers to exhaust process memory via a crafted MP4 file. AP4_Processor::Process leaves atom objects allocated when AP4_AtomFactory parses the malformed input, as LeakSanitizer records 328 leaked bytes. Exploitation requires a user or workflow to pass the crafted file to mp4decrypt; repeated processing can deplete resources and interrupt that process.
