Name of the Vulnerable Software and Affected Versions Open Design Alliance Drawings SDK versions prior to 2022.11

Description A Use-After-Free Remote issue exists when reading a DWG file using the parsing functionality. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this to execute code in the context of the current process.

Recommendations For versions prior to 2022.11, update to a version 2022.11 or later to resolve the issue. As a temporary workaround, consider restricting the use of DWG file parsing functionality until a patch is available. Avoid using the Drawings SDK to parse untrusted DWG files until the issue is resolved.
