CVE-2022-36186Public exploitNetwork attack vector

Process crash via unchecked output PID

Published Aug 17, 2022 · Updated Aug 3, 2024

NULL pointer dereference in GPAC 2.1-DEV allows remote attackers to crash the MP4Box process with a crafted media file. The Dolby Vision NALU path proceeds with a NULL output PID, causing gf_filter_pid_set_property_full to access a member through that pointer. Processing attacker-supplied media is required; successful exploitation terminates the MP4Box process without reported data disclosure or modification.
