Code execution via undisclosed heap buffer overflow
Published Sep 12, 2023 · Updated Oct 30, 2025
Heap-based buffer overflow in Microsoft 3D Viewer before 7.2306.12012.0 allows attackers to execute arbitrary code after user interaction. The CNA identifies the weakness class, but Microsoft has not published the affected parser, buffer operation, or attacker-controlled input that overruns the heap. Exploitation requires a user action, and successful code execution can take control of data and interrupt the application in that user 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=7.0.0 <7.2306.12012.0
