CVE-2022-43044Public exploit

Process crash via unchecked file-location pointer dereference

Published Oct 19, 2022 · Updated May 9, 2025

Out-of-bounds memory access in GPAC MP4Box 2.1-DEV-rev368-gfd054169b-master allows attackers to crash it via a crafted ISO file. gf_isom_get_meta_item_info dereferences meta->file_locations and its dref member for a nonzero data-reference index without confirming either pointer exists. A local user must make MP4Box inspect the file; the demonstrated result is an aborting segmentation fault, not data disclosure or modification.
