On September 9, TechRepublic launched a new feature within our Microsoft Windows blog, Windows Patch Tuesday. Each month, Justin James will go through the latest batch of Windows patches and provide a clear and concise summary of each. Justin will scour Microsoft’s Knowledge Base and other resources to bring you the information that you need to make decisions on whether or not to apply these patches.

Clear and concise roundup

Here are a few examples from our Windows Patch Tuesday: September 2008 post:

MS08-052/KB954593 – Critical: This patch addresses an issue in GDI+ (the graphics subsystem) where malformed images could be used to create a stack overflow, which in turn would let an attacker get control of the system. It is aimed at all versions of Windows and should definitely be installed. There are also a number of patches not just for Windows, but for non-Windows products such as the .Net Framework (1.0 – 2.0) and Visual Studio to correct the same vulnerability. These additional patches are listed in the KB article.

KB947821: This is an update to the Vista and Windows Server 2008 System Readiness Tool. The System Readiness Tool checks a system out to make sure that there are no inconsistencies in the registry, file system, etc. that would cause updates to fail. Ironically, this patch fixes some issues that it was having, where on occasion it would hang or not work right and prevent updates from installing. It’s not critical, and you probably won’t need it unless you have been having problems.

KB956697: Apparently, Hyper-V has been having problems with its Volume Shadow Copy hooks, which are keeping it from backing up VMs properly on systems running Windows Server 2008 x64. This patch fixes that. If you are using x64 Windows Server 2008 and Hyper-V, install this one pronto! Otherwise, don’t sweat it.
