CVE-2022-36190Public exploit

Process crash via freed sample-entry dereference

Published Aug 17, 2022 · Updated Aug 3, 2024

Use-after-free in GPAC MP4Box 2.1-DEV-revUNKNOWN-master allows context-dependent attackers to crash its process via a crafted media file. While nested boxes are parsed, unkn_box_read frees a sample-entry allocation that gf_isom_dovi_config_get later dereferences for an eight-byte read. The demonstrated path requires MP4Box to inspect attacker-supplied media with its info operation; the published proof shows an abort, not code execution.
