CVE-2021-42023 (GCVE-0-2021-42023)

Vulnerability from cvelistv5 – Published: 2021-12-14 00:00 – Updated: 2024-08-04 03:22
VLAI?
Summary
A vulnerability has been identified in ModelSim Simulation (All versions), Questa Simulation (All versions). The RSA white-box implementation in affected applications insufficiently protects the built-in private keys that are required to decrypt electronic intellectual property (IP) data in accordance with the IEEE 1735 recommended practice. This could allow a sophisticated attacker to discover the keys, bypassing the protection intended by the IEEE 1735 recommended practice.
Severity ?
No CVSS data available.
