Authenticated memory disclosure via out-of-bounds read
Published Jan 10, 2023 · Updated Jan 1, 2025
Out-of-bounds read in Microsoft Office Visio allows remote authenticated users to disclose sensitive process memory via unspecified input. Microsoft has not published the affected parser or routine, the input field that crosses a boundary, or how returned memory reaches the attacker. Low-privileged network access is required; the documented outcome is memory disclosure with a possible service interruption, not data modification.

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.
