On Friday, we noted that Apple had taken the rare step of using its anti-malware tools in OS X to disable existing installations of the Java 7 browser plug-in due to a major security vulnerability that was being actively exploited in the wild. Apple’s anti-malware system is capable of enforcing minimum version numbers for plug-ins such as Java and Flash, and Apple simply updated its blacklist information to require that machines be running a higher version of the Java 7 plug-in than was publicly available.
Oracle has now released Java 7 Update 11, and the release notesindicate that it does indeed address the vulnerability. The new release registers with a version string of 1.7.0_11-b21, satisfying Apple’s requirement for a minimum version number of 1.7.0_10-b19.
In addition to the fix for the vulnerability, Java 7 Update 11 also sees a change in the default security level setting from “Medium” to “High”. Under the new setting, users will be warned before the Java plug-in runs any unsigned application.
