CVE-2022-47086Public exploit

Process crash via unchecked SWF header error

Published Jan 5, 2023 · Updated Apr 10, 2025

Out-of-bounds read in GPAC MP4Box 2.1-DEV-rev574-g9d5bb184b allows local users to crash MP4Box by importing a crafted SWF file. gf_sm_load_init_swf ignores gf_swf_read_header's error return, then reads invalid SWF reader width and height values after header parsing fails. A user or application must cause the local MP4Box process to import the file; the demonstrated consequence is a process crash, not data disclosure or modification.
