Java Vulnerability Found
A new 0-day Java vulnerability has been discovered that is already being used in malware distribution kits “in the wild.” No update to fix the problem is yet available.
Naked Security has provided an overview of the vulnerability along with links to instructions on how to disable the Java extensions in all major browsers until an update is released. These extensions are the vector for attack via malicious web sites, so it may be a good idea to disable them, at least temporarily.
For convenience, here are the links for each browser:
Internet Explorer
Firefox
Google Chrome
Safari
Opera
The first line of defence, of course, is always to be careful not to visit suspicious web sites in the first place.
