Is Linux vulnerable to Java drive-by exploits?
Another computer I run on windows 7 just notified me that it was infected through Java, and I'm wondering if my Linux box (ubuntu 10) with Java installed is vulnerable.
That depends on which operating system is the target of the virus. Linux is less likely to be the target, but some viruses do target Linux as well, and some are even multi-platform.
Your browser should not be configured to automatically execute and trust Java applets. Although Chrome is the youngest browser, some protections are already available.
Plug-ins that you do not use should be disabled:
I suggest installing at least the NotScripts extension as an immediate protection.

So, yes, it is possible, but very rare. You can always do a ClamAV/ClamTk scan wich can be downloaded from ubuntu software center or here
But i think Click-to-play is secure enough
