Are you vulnerable to the latest Java 0-day exploit?
Test to see if you're vulnerable.
The DeepEnd Research have been in contact with Michael Schierl
the Java expert who discovered a number of Java vulnerabilities,
including recent the Java Rhino CVE-2011-3544 / ZDI-11-305 and
CVE-2012-1723. We asked him to have a look at this last exploit .
Michael sent his detailed analysis, which we will publish in the nearest
future and a patch , which we offer on a per request basis today.
The Fix
There is no fix yet. The solution is disable Java plugin in all your browser to prevent malicious applets from running. The latest iteration of Java is version 1.7 revision 6. This is now the default version on Windows. Mac OS X still uses Java 1.6 (latest version: 1.6.33). Java 1.6.33 is NOT vulnerable to the latest 0-day exploit. However, I would not suggest that anybody downgrade from Java 1.7 to Java 1.6 as it is not yet known if version 1.6 is vulnerable to other flaws fixed in 1.7.
