CVE-2022-3810Public exploitNetwork attack vector

Process crash via null atom dereference

Published Nov 1, 2022 · Updated Apr 15, 2025

NULL-pointer dereference in Bento4 1.6.0-639 mp42hevc allows remote attackers to crash the tool by supplying a crafted MP4 file. A malformed MP4 reaches atom->GetType with a null atom in AP4_File::ParseStream, causing a read from the zero page. Execution requires a user or downstream workflow to pass the attacker-controlled file to mp42hevc; the observed consequence is termination of that process.
