Note that Microsoft is about to release an out-of-band update for the Internet Explorer vulnerability detailed here.

This will come 15th January 2013 7am New Zealand time.

Internet Explorer 9 and Internet Explorer 10 are not affected.

For those who don't know "out-of-band" it means out of the usual cycle of "second Tuesday of the month Windows Update releases" (second Wednesday of the month New Zealand time). Microsoft only releases out-of-band updates for security issues that need immediate attention.

Windows Update should automatically install this if enabled.
