Security Update 2013-001 for Snow Leopard and Lion

Apple has released Security Update 2013-001 for Mac OS X 10.6 Snow Leopard and 10.7 Lion, with each big cat getting two versions: Snow Leopard (316.63 MB) and Snow Leopard Server (391.63 MB); and Lion (31.42 MB) and Lion Server (79.33 MB). The updates close a variety of vulnerabilities, including Apache HTTP authentication, handling of JSON data by Ruby on Rails in Podcast Producer Server, and a buffer overflow when viewing MP4 files in QuickTime. The complete list of fixes can be found on this Apple support page, which combines the details for these security updates with those for the just-released Mountain Lion update (see “OS X 10.8.3 Mountain Lion Fixes Nagging Bugs,” 14 March 2013). The security update also runs a malware removal tool that will notify you only if anything is removed. It’s interesting to see Apple releasing this update for 10.6 Snow Leopard, since Apple generally maintains security updates only one version behind the current cat. (Free)
