Apple has, however, apparently already moved quickly to address the issue, disabling the Java 7 plug-in on Macs where it is already installed. Apple has achieved this by updating its "Xprotect.plist" blacklist to require a minimum of an as-yet unreleased 1.7.0_10-b19 version of Java 7. With the current publicly-available version of Java 7 being 1.7.0_10-b18, all systems running Java 7 are failing to pass the check initiated through the anti-malware system built into OS X.

The U.S. Department of Homeland Security has warned users to disable or uninstall Java software on their computers, amid continuing fears and an escalation in warnings from security experts that hundreds of millions of business and consumer users are vulnerable to a serious flaw.
