Actually, it is rather more like the Zotob vuln than the Blaster vuln. It is a crit on earlier systems, but requires authenticated privledges on Vista and 2K8 server due to the implementation of the integrity level defenses in Vista and 2K8. That said, the potential for damage with this vulnerability is high and there were reports of attacks in the wild. Thus, Microsoft released out of the standard release cycle.
