Microsoft has issued a special “Fix It” patch for the recently-discovered vulnerabilities in older versions of Internet Explorer.

The original security advisory has been updated to include a link to the fix.

Anyone still using Internet Explorer 6, 7 or 8 should install the fix or stop using IE immediately.

Update 2013-Jan-05: According to the Internet Storm Center, the temporary workaround provided by this Fix-It from Microsoft has already been rendered ineffective by means of a bypass.
