First Patch Tuesday August 2011: Lucky 13?

A quick look at Microsoft’s Security Bulletin Summary for August 2011 shows 13 security bulletins for this morning. My own machines (both 32- and 64-bit Windows versions) showed a nearly uniform list of 14 security bulletins (including some non-bulletin elements like the monthly refresh of the Windows Malicious Software Removal Tool and a keyboard driver for my Microsoft keyboards).

Key to [xx] bracketed ratings information
   First char describes severity ranking: C = Critical, I = Important, M = Moderate
   Second char labels restart: R = requires restart, M = may require restart

MS11-058 deals with DNS servers and is highly unlikely to show up on Windows client computers, but the rest of this sometimes comes in separate 32- or 64-bit versions, all of which are likely to show up on Windows desktop machines. There will be some serious and meaningful work for system admins to get these updates into testing to determine if and when deployment will be necessary (as will probably prove to be the case for all critical and important updates in the list, where they touch functions that are present on specific Windows clients or reference builds).

For those who use automatic update, please note that there are two .NET Framework items that remain unselected for install by Microsoft’s choice: KB2468871 and KB2533623. These will need to selected for manual installation if they show up on client machines (as they will for most ordinary Windows users).
