CVE-2022-27145Public exploit

Process crash via unbounded sample-time recursion

Published Apr 8, 2022 · Updated Aug 3, 2024

Stack overflow in GPAC MP4Box 1.1.0-DEV-rev1727-g8be34973d-master allows local users to crash the process via a crafted media file. The sample-time lookup recurses when nextMediaTime moves in the wrong direction for the selected search mode, exhausting the call stack. Exploitation requires MP4Box to process attacker-supplied content with the -frag operation; the demonstrated consequence is a process crash.
