CVE-2022-46489Public exploit

Memory exhaustion via unreleased compressed-box buffers

Published Jan 5, 2023 · Updated Apr 10, 2025

Memory exhaustion in GPAC 2.1-DEV-rev505-gb9577e6ad-master allows local users to interrupt MP4Box via a crafted MP4 file. During compressed ISO box parsing, gf_isom_box_parse_ex allocates buffers from attacker-controlled box data and leaves them allocated after decompression rejects the payload. A user must make MP4Box inspect the crafted file; the demonstrated leak consumes about 1.7 GB and can interrupt the process or competing workloads.
