CVE-2026-95122 Details
Description
mp4v2 2.0.0 contains a NULL pointer dereference vulnerability in MP4File::GenerateTracks() in src/mp4file.cpp. This allows a remote attacker to cause a denial of service
A NULL pointer dereference vulnerability has been identified in mp4v2 version 2.0.0. The issue arises in the 'MP4File::GenerateTracks()' function within 'src/mp4file.cpp'. This vulnerability allows remote attackers to cause a denial-of-service by sending a malformed 'trak/mdia/hdlr' structure that leaves the track handler type unset. 'GenerateTracks()' then passes the resulting NULL handler-type pointer directly to 'strcmp()' without proper validation, leading to undefined behavior and process termination.
Users can update to the latest version of mp4v2, where this vulnerability has been fixed. Instructions for downloading the patched version are available on the project's GitHub page.
