**Name of the Vulnerable Software and Affected Versions** Mac OS X versions prior to 10.6.2 **Description** The issue is related to the kernel's handling of task state segments, allowing local users to gain privileges, cause a system crash, or obtain sensitive information. **Recommendations** For versions prior to 10.6.2, update to version 10.6.2 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Dovecot versions 1.0 through 1.0.3 Dovecot versions 1.1 through 1.1.6 **Description** The issue allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via a crafted SIEVE script. This can be demonstrated by forwarding an e-mail message to a large number of recipients. **Recommendations** For Dovecot versions 1.0 through 1.0.3, update to version 1.0.4 or later. For Dovecot versions 1.1 through 1.1.6, update to version 1.1.7 or later.
