CVE-2023-22669

Code execution via oversized XRecord heap copy

Published Apr 15, 2023 · Updated May 5, 2025

Heap-based buffer overflow in Open Design Alliance Drawings SDK before 2023.6 allows attackers to execute code via a crafted DWG file. The DWG parser trusts a user-supplied XRecord length and copies that data into a fixed-length heap buffer without first validating that it fits. Exploitation requires a user or host application to open the malicious drawing, after which code runs in the current process context.
