Code execution requiring user interaction
Published Sep 10, 2024 · Updated Aug 10, 2026
Remote code execution in Windows libarchive allows local users to execute code through an undisclosed local vector requiring user interaction. Microsoft identifies an integer overflow or wraparound in the Windows libarchive component but has not published the affected function, arithmetic operation, or input format. Exploitation requires low-privileged local access and user interaction; no higher privilege context is publicly specified.
