Alongside release of iOS 4.3.2, Apple also released Safari 5.0.5 and Security Update 2011-002 for Mac OS X. Safari 5.0.5 seems to simply include the latest security updates. The updates are available through Apple's download pages and through Software Update. Security Update 2011-002 is a small download for Snow Leopard users, but the Leopard versions are far and away larger files including even more changes than their Snow Leopard counterparts.
