ZDNet is reporting that exploit code for a critical (remotely exploitable) vulnerability in Microsoft’s Internet Explorer 6 and 7 browsers has been released on the Internet.
Be sure to upgrade to IE8 before a worm is in the wild.
Also, please do internet a favor, and spread the word to your readers. It would greatly benefit all websites if IE6 and IE7 usage dropped as a result of this.
Update: It seems that Opera users are hardly any better off, today.
