CVE-2022-3812Public exploitNetwork attack vector

Service interruption via unreleased parsed atoms

Published Nov 1, 2022 · Updated Aug 3, 2024

Memory leak in Bento4 1.6.0-639 mp4encrypt allows remote attackers to interrupt processing via a crafted MP4 file. While AP4_ContainerAtom parses nested atoms, AP4_EsdsAtom objects allocated from the untrusted file remain unreleased after parsing. A user must cause mp4encrypt to process the file; repeated processing consumes memory and can interrupt the tool, without reported data disclosure or modification.
