To bring the security fixes from Mac OS X 10.7.2 Lion back to 10.6 Snow Leopard, Apple has released Security Update 2011-006 (Snow Leopard) and Security Update 2011-006 (Snow Leopard Server). The security vulnerabilities addressed are many and varied, with numerous affected components. Plus, Apple has updated a number of root SSL/TLS certificates. We recommend these updates for anyone still running Snow Leopard; it’s easiest to let Software Update install the correct version for you.
