Schmitz Apple has released Security Update 2013-002 for Mac OS X 10.6 Snow Leopard and 10.7 Lion, with each of the operating system updates getting two versions: [1]Snow Leopard (329.85 MB) and [2]Snow Leopard Server (404.83 MB); and [3]Lion (57.69 MB) and [4]Lion Server (105.61 MB). Several of the security changes are the same as those added to the just-released update to Mountain Lion (see '[5]OS X 10.8.4 Mountain Lion Finally Fixes Messages,' 5 June 2013), which shares its [6]security overview page with the 2013-002 security updates. (Be sure to look at the 'Available for' line under each of the changes to see if it pertains to your system.) Across all the big cats, the security updates close vulnerabilities related to OpenSSL and QuickTime, while Snow Leopard gets targeted fixes for vulnerabilities to Directory Service and Ruby on Rails.
