CVE-2021-42023

Name of the Vulnerable Software and Affected Versions ModelSim Simulation (all versions) Questa Simulation (all versions)

Description A vulnerability has been identified that affects the RSA white-box implementation in the affected applications. This vulnerability insufficiently protects the built-in private keys required to decrypt electronic intellectual property (IP) data in accordance with the IEEE 1735 recommended practice. As a result, a sophisticated attacker could potentially discover the keys and bypass the intended protection.

Recommendations For ModelSim Simulation (all versions), consider restricting access to the private keys until a proper fix is implemented. For Questa Simulation (all versions), avoid using the affected RSA white-box implementation for decrypting electronic intellectual property (IP) data until the issue is resolved.
