The hits just keep on coming for Java. As fast as Oracle/Sun plugs (or tries, but fails to plug) one hole, another is discovered by independent security researchers.
This time, it’s the security research team at FireEye that have found vulnerabilities in the latest Java, version 7u15, as well as the most recent 6-series version (6u41).
Making matters worse, the new vulnerability is being actively exploited in the wild: a remote access trojan is being installed on affected computers.
In other words, even if you have the latest version of Java, you can be hit by this exploit. As always, if you don’t actually need Java enabled in your browser, disable it. If that’s not an option, be extremely wary of browsing web sites that you don’t know for sure are safe.
