Lifecycle Timeline
6DescriptionCVE.org
A security vulnerability has been detected in justdan96 tsMuxer up to 2.7.0. This issue affects the function VvcVpsUnit::setFPS of the file tsMuxer/vvc.cpp. Such manipulation of the argument track_id leads to denial of service. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. This vulnerability only affects products that are no longer supported by the maintainer.
AnalysisAI
Denial of service in tsMuxer up to version 2.7.0 via improper handling of the track_id argument in the VvcVpsUnit::setFPS function allows local authenticated attackers to trigger an availability impact. Publicly available exploit code exists; however, the vulnerability affects only unsupported legacy versions and requires local access with user-level privileges, limiting real-world exposure.
Technical ContextAI
tsMuxer is a multimedia multiplexer tool that processes video and audio streams. The vulnerability resides in the VVC (Versatile Video Codec) parsing logic, specifically in the VvcVpsUnit::setFPS function within tsMuxer/vvc.cpp. The root cause is classified as CWE-404 (Unimplemented or Unsupported Feature in Parser), indicating that the parser fails to properly validate or handle the track_id parameter when setting frame rate information for VVC codec streams. This lack of input validation or bounds checking allows a crafted malformed media file to trigger an exception or resource exhaustion condition when processed locally.
RemediationAI
No vendor-released patch is available for this vulnerability, as tsMuxer 2.7.0 and earlier versions are no longer supported by the maintainer. Users of legacy tsMuxer installations should immediately upgrade to the latest available version if support has resumed, or discontinue use of the affected software and migrate to a maintained multimedia multiplexing tool (such as FFmpeg or HandBrake for common use cases). If discontinuation is not feasible and the application processes untrusted media files, implement strict file validation and sandboxing: restrict tsMuxer execution to a dedicated unprivileged user account with minimal file system access, disable VVC codec processing if not essential, and scan input files with antimalware or media-file validators before processing. Monitor process execution logs for abnormal terminations or resource spikes indicating exploitation attempts. Note that these compensating controls mitigate impact but do not eliminate the underlying vulnerability.
