CVE-2022-27146Public exploit

Application crash via Apple metadata over-read

Published Apr 8, 2022 · Updated Aug 3, 2024

Heap-buffer overflow in GPAC MP4Box 1.1.0-DEV-rev1759-geb2d1e6dd allows local users to crash MP4Box via a crafted MP4 file. During file fragmentation, gf_isom_apple_enum_tag reads one byte beyond a five-byte heap region allocated while parsing Apple metadata. A user must cause MP4Box to process the file; the demonstrated consequence is an AddressSanitizer abort and application crash.
