CVE-2022-29119

Code execution after 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 attackers to execute code after local user interaction. Microsoft identifies the affected codec package and interaction requirement but has not published the decoder locus or unsafe operation performed on media input. A user must open affected content locally, after which code executes with that user's privileges and can compromise data or interrupt applications.
