Information disclosure via OBJ parser out-of-bounds read
Published Jun 13, 2023 · Updated Jan 1, 2025
Out-of-bounds read in Microsoft Visual Studio allows local users to disclose process memory by supplying a crafted OBJ file. The OBJ file parser reads beyond a buffer boundary while processing malformed object data, exposing adjacent process memory. Exploitation requires local access and user interaction to process attacker-controlled content; no integrity or availability impact is reported.

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.
