This concerns me. Fear associated with the patching process has the potential to be one of the greatest weaknesses in the overall security of organizations. If a business is afraid to apply patches due to potential vulnerabilities in WSUS, then a significant battle is lost and all of the organization’s end points are at risk. And from this demonstration at Black Hat, there is a solution in the form of SSL with proper certificate management, but Microsoft has placed that burden on the end user organization. This issue should be addressed and it should be addressed quickly.
