CVE-2022-45283Public exploit

Process crash via unbounded SVG timing copy

Published Dec 5, 2022 · Updated Apr 24, 2025

Stack-based buffer overflow in GPAC MP4Box 2.0.0 allows local users to crash the process by processing a crafted SVG file. The smil_parse_time_list function copies an unbounded semicolon-delimited SVG timing value into a 500-byte stack buffer. A user must invoke MP4Box on the file; the published proof of concept demonstrates process termination from stack-buffer corruption.
