Please update your Windows machine now if you haven’t already. Microsoft released an out-of-band update to patch a critical hole that is present in all versions of Windows. Vista and Server 2k8 users are at a slightly less risk since “the vulnerable code path is only accessible to authenticated users” – but still, if you haven’t updated, do it now! This is not an everyday type of vulnerability, but rather a widespread wormable hole that has serious implications if it remains unpatched.
