Critical Microsoft Security update

The first update of the new year from Microsoft starts with a critical update affecting all the Windows platforms. Microsoft lists two vulnerabilities on this Bulletin, the more critical one is the IGMP vulnerability which is enabled by default on all Windows XP SP2 machines. On corporate networks, even though IGMP could be blocked at the perimeter, a worm infected PC could be used as a jumping point to exploit other machines. So patch ASAP
