* These Ahead-of-the-Threat signatures are blocked by default and analyze Java applet class files for classes and methods that may indicate an attempt to call the security manager with the intent of extending applet permissions. 

Additional recommendations: We would recommend disabling Java in browsers, and if absolutely necessary selectively turning it on for trusted sources.  

Detailed Description

Business Impact:

Successful exploitation of this vulnerability would provide an attacker with complete control of the victim's machine.  Public exploits are currently available and these vulnerabilities are also being exploited by popular exploit kits. Customers that are using the Java 7 web browser plugin should consider immediate deployment of patches available at for this issue. Customers using Java release  6 or earlier are highly encouraged to move to Java 7 as Oracle is no longer releasing public updates for Java 6. Our previous guidance indicated that without the availability of a patch, installing another web browser with the Java plugin disabled would have a suitable remediation effect.
