Time to Patch Java

Java Patch Released

As you may have heard there is a significant security vulnerability in Java that is currently being exploited widely on the internet. This bug can be used to silently install keyloggers or other types of malicious software from compromised websites. Oracle has released a patch that you should install as soon as possible on all your computers and servers.

In addition, security researchers are recommending that you disable Java functionality in your web browser after installing the patch. This will help limit your exposure to bugs that will be exploited in the future.

You can download the patch here and then read below for instructions on how to disable java in your web browser.
