If you use Java, you can either uninstall/disable the plugin to protect your computer or set your security settings to 'High' and attempt to avoid executing malicious applets. This latest flaw was first discovered by security firm FireEye, which says it has already been used 'to attack multiple customers.' The company has found that the flaw can be exploited successfully in browsers that have Java v1.6 Update 41 or Java v1.7 Update 15 installed, the latest versions of Oracle's plugin."
