Apple today released patches for most (all?) of its operating systems. For more details from Apple, see http://support.apple.com/kb/ht1222.

- OS X has been updated to 10.9.4 (Security Update 2014-003). The security update is also available for older versions of OS X.
- Safari has been updated to 6.1.5 and 7.0.5
- iOS has been updated to 7.1.2
- Apple TV has been updated to 6.2.

The largest common source of patches for all of these products is WebKit. The updates should be applied in a timely manner. There is no indication at this point about active exploits. The iOS update also patches a problem that would allow an attacker to bypass activation lock, as well as an lock screen bypass that has been demoed publicly a couple weeks ago.
