Oracle has released an emergency Java patch addressing the latest in-the-wild exploit targeting the software. The company suggests users apply this update "as soon as possible" due to "the severity of these vulnerabilities." The full patch description and download is available through Oracle's Technology Network (you can also get the patch through the software's auto-update).
This particular vulnerability is being exploited to install a remote-access trojan dubbed McRat. The attacks targeted Java versions 1.6 Update 41 and 1.7 Update 15, which are the latest available releases of the widely used software. Security Editor Dan Goodin reported on the issue just three days ago, as attacks were being triggered when people with a vulnerable Java version visited a booby-trapped website.
It almost goes without saying—Java security has left something to be desired lately. High profile companies such as Facebook, Apple, and Twitter all fell at the hands of Java recently. These businesses disclosed that their computers were compromised by exploits later linked to a developer website hacked into a platform for Java exploits.
