imageToday, we released six security bulletins addressing a total of 15 vulnerabilities. Four affect Windows and Windows Server and two affect Microsoft Office products (Excel and Word).

As we do every month, we have prepared our Risk & Impact and our Deployment Priority guidance to help customers assess risk to their environments and prioritize the deployment of this month’s updates. Risk & Impact is a snapshot of the cumulative severity and exploitability index ratings for each bulletin. This month, MS09-065 is the only bulletin with a critical severity rating and an Exploitability Index rating of 1 (“Consistent Exploit Code Likely”). This bulletin provides updates for three vulnerabilities in Windows Kernel-Mode Drivers. We recommend customers prioritize and deploy this update immediately.
