[Update: Mozilla joins in, FBI issues warning, fix coming] Apple has disabled the Java 7 browser plug-in on Macs through an updated OS X blacklist file, notes MacRumors. Recently a major security vulnerability
was discovered in Java 7, one already being exploited in malware. In response, Apple has silently pushed
an updated Xprotect.plist file to OS X users, setting an as-yet-unreleased v1.7.0_10-b19 as the minimum version of Java required for unrestricted operation.
