YAJZE: Yet another Java Zero-Day Exploit

Unfortunately, it is really the case to say that Java has “yet another zero-day exploit”.

The latest version of Java, v7 Update 10 is affected and currently there is no plan for a patch. The vulnerability which is already used in online attacks is a code injection onto a fully patched Windows system running the affected Java version. It is not known yet if other versions of Java are affected. In order to get affected, somebody has to visit a website running the exploit applet which performs the code injection.

If in the meantime you re-activated the Java plugin in your  browser since the last zero-day exploit at the end of August 2012, here is how to deactivate it again:

• Deactivate the Java plugin in Chrome
• Deactivate the Java plugin in Firefox
• Deactivate the Java plugin in Safari
• Deactivate the Java plugin in IE: it is very tricky. I will write a detailed article about how to do this. Don’t simply think that by deactivating the plugin in the Add-ons list of IE does the job, as anybody would expect. Until then, please uninstall Java from your system through “Programs and features” or “Add and remove Programs”.
