**Name of the Vulnerable Software and Affected Versions** Mail in Apple Mac OS X versions prior to 10.6.3 **Description** The issue is related to the improper enforcement of the key usage extension during the processing of a keychain that specifies multiple certificates for an e-mail recipient. This might make it easier for remote attackers to obtain sensitive information via a brute-force attack on a weakly encrypted e-mail message. **Recommendations** For Mail in Apple Mac OS X versions prior to 10.6.3, update to version 10.6.3 or later to resolve the issue.
