CVE-2022-40885Public exploit

Service crash via unbounded media allocation

Published Oct 19, 2022 · Updated May 9, 2025

Resource exhaustion in Bento4 1.6.0-639 allows local users to crash media-processing tools by opening a crafted media file. Affected parsers use untrusted length fields directly as AP4_DataBuffer or AP4_HdlrAtom heap-allocation sizes, causing multi-gigabyte allocation requests. The attack requires a user or local workflow to process the crafted file; allocation failure aborts the affected command without reported data disclosure or modification.
