Code execution requiring local user interaction
Published Jun 15, 2022 · Updated Jan 2, 2025
Remote code execution in Microsoft HEVC Video Extensions before 2.0.51121.0 allows local users to execute code after user interaction. Microsoft also identifies HEVC Video Extension before 2.0.51122.0 as affected, but has not disclosed the flawed decoder locus or its unsafe operation on media input. Exploitation requires local access and user interaction; successful exploitation runs attacker-controlled code in the affected application context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=1.0.0.0 <2.0.51122.0
- Affected versionversion=1.0.0 <2.0.51121.0
