**Name of the Vulnerable Software and Affected Versions** Mac OS X versions prior to 10.6.8 **Description** The issue concerns the Certificate Trust Policy component, which fails to perform CRL checking for Extended Validation (EV) certificates lacking OCSP URLs. This might allow man-in-the-middle attackers to spoof an SSL server via a revoked certificate. **Recommendations** For Mac OS X versions prior to 10.6.8, update to version 10.6.8 or later to resolve the issue. As a temporary workaround, consider restricting the use of EV certificates that lack OCSP URLs to minimize the risk of exploitation.
