Apple has released a new Java update for OS X, marking the second Java update in the course of two days. The update is likely in response to the Flashback trojan found to be affecting 600,000 Macs.
Java for OS X 2012-002 delivers improved compatibility, security, and reliability by updating Java SE 6 to 1.6.0_31.
Please quit any web browsers and Java applications before installing this update.

The update weights in at 66.6MB (66.6 – spooky!), and is available immediately through Software Update.
