Microsoft has released a patch for Internet Explorer. Apparently, there was enough of a concern for them to move outside of their regular patch schedule.
If you are using IE7 on Windows XP with SP2 or SP3, you can find the patch here.
If you are using IE7 on Windows Vista or Vista with SP1, you can find that here.
If you are running Internet Explorer on any other configuration, you can find your configuration on the Microsoft Security Bulletin MS08-078 here.
If you are running any combination of Internet Explorer on a Microsoft Operating system, you are strongly encouraged to install the patch.
