Yep, aside from a new iOS, Apple has also released a Java update for OS X.
This update is available for Macs running on OS X v10.6.8 (Snow Leopard), OS X Server v10.6.8, OS X Lion v10.7 or later, OS X Lion Server v10.7 or later, and of course, OS X Mountain Lion 10.8 or later.
This one’s highly recommended as it address a vulnerability discovered in Java 1.6.0_37, where an untrusted Java applet could execute a code with the privileges of the current user. In short, this is a serious security flaw that needs patchin’ ASAP.
To download, just hit the Software Update button from the drop down menu when you click the Apple logo at the upper left hand corner.
