CVE-2022-1222Public exploit

Media-processing hang via AVI length integer wrap

Published Apr 4, 2022 · Updated Aug 2, 2024

Infinite-loop handling in GPAC before 2.1.0-DEV allows local users to hang media processing with a crafted AVI file. The avidmx path passes a crafted 0xfffffff8 header size to avi_parse_input_file, whose 32-bit loop index wraps while compared with a 64-bit length. Triggering requires processing the malicious AVI through the avidmx filter; the loop consumes processing capacity without exposing or modifying data.
