A vulnerability in all popular versions of Internet Explorer running on Windows XP, Vista, and Windows 7 is being exploited by a targeted attack, originating in China. The attack appears to be in response to the possibility of Google pulling out of China because of Internet censorship. This vulnerability will allow the attacker to take over the computer if the user is duped into clicking on a link in a web page, email or instant messenger chat.

Microsoft is working on a fix which they hope will be ready by next Tuesday.
