Base vector

AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

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

Description The issue exists within the parsing of DGN files, where crafted data and lack of proper validation of input data can trigger a write operation past the end of an allocated buffer. This can allow an attacker 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 DGN file parsing functionality until a patch is available. Avoid using the Drawings SDK to parse crafted or untrusted DGN files until the issue is resolved.
