Unlike Microsoft, Apple has so far not committed to a regular patch cycle, and today's release of IOS 4.3.2 as well as the OS X Security Update 2011-002 came somewhat as a surprise. 
Both include security fixes that should be applied rather sooner then later. The OS X update also includes Safari 5.0.5 . We will update this diary once the Apple support page with security details is live.
The patch is pretty small compared to other Apple patches (about 4 MB). You need to restart your system after applying the security patch. I applied it to one system with PGP full disk encryption, and so far no ill effects.
