Schmitz Apple released Security Update 2013-001 for Mac OS X 10.6 Snow Leopard and 10.7 Lion, with each big cat getting two versions: [1]Snow Leopard (316.63 MB) and [2]Snow Leopard Server (391.63 MB); and [3]Lion (31.42 MB) and [4]Lion Server (79.33). 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 [5]Apple support page, which combines the details for these security updates with those for the just-released Mountain Lion update (see '[6]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.
