CVE-2022-43037Public exploitNetwork attack vector

Process-memory consumption via unreleased ParseStream allocation

Published Oct 19, 2022 · Updated May 8, 2025

Memory leak in Bento4 1.6.0-639 allows remote attackers to consume unreleased process memory by inducing a user to process a crafted media file. AP4_File::ParseStream allocates a 64-byte object while mp42aac parses the crafted input and fails to release that allocation. Exploitation requires user interaction; the published reproduction demonstrates the leak but does not document a crash or full memory exhaustion.
