CVE-2022-38530Public exploit

Application crash via recursive ISOM_IOD parsing

Published Sep 6, 2022 · Updated Aug 3, 2024

Stack overflow in GPAC 2.1-DEV-rev232-gfcaa01ebb-master allows attackers to crash MP4Box by processing a crafted ISOM_IOD file. The ISOM_IOD reader repeatedly cycles through descriptor parsing functions without limiting nested descriptor depth, exhausting the process stack. The crash requires MP4Box to run its hinting path on the crafted file; the published report demonstrates process termination, not code execution.
