CVE-2022-43045Public exploit

Process crash via null scene-field dereference

Published Oct 19, 2022 · Updated May 9, 2025

Null pointer dereference in GPAC 2.1-DEV-rev368-gfd054169b-master allows local users to crash MP4Box through a crafted ISO media file. The gf_dump_vrml_sffield function in scene_manager/scene_dump.c reads through a null scene-field pointer while MP4Box dumps a malformed BIFS scene. Exploitation requires user interaction to make MP4Box process the file and interrupts only the invoked process, with no reported data disclosure or modification.
