Code execution via GLB parser out-of-bounds read
Published Jun 8, 2021 · Updated Aug 3, 2024
Out-of-bounds read in Microsoft Paint 3D before 6.2105.4017.0 allows remote attackers to execute code through a malicious GLB file. The GLB parser insufficiently validates user-supplied data before reading beyond the end of an allocated data structure. Exploitation requires the target to visit a malicious page or open a malicious file, and resulting code runs in the current low-integrity process.

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.
