CVE-2022-43042Public exploit

Process crash via out-of-bounds SDTP read

Published Oct 19, 2022 · Updated May 9, 2025

Heap buffer overflow in GPAC 2.1-DEV-rev368-gfd054169b-master allows local users to crash MP4Box with a crafted media file. FixSDTPInTRAF reads one byte past a four-byte sdtp allocation while reconciling sample dependency data in a malformed traf box. The victim must direct MP4Box to parse the file; the published proof of concept demonstrates an AddressSanitizer abort without establishing code execution.
