Patch Tuesday: August 2011

With this August Microsoft Patch Tuesday update, we see a moderate set of updates in comparison to those lists of updates released by Microsoft for the months of June and July. In total there are 13 Microsoft Security Updates with the following rating; 2 rated as Critical, 9 rated as Important and 2 as Moderate by Microsoft. Given the scope and nature of this month’s update, the ChangeBASE team expects to find a small number of issues raised by the AOK Automated Patch Impact Assessment. In particular, Microsoft Security Update M11-060 will require careful testing prior to deployment due to the core operating system DLL’s contained within this update.

Given the nature of the changes and updates included in each of these patches, most systems will require a reboot to successfully implement any and all of the patches and updates released in this August Patch Tuesday release cycle.
