More information about this security update

In addition to the product version that is specified in the "Applies to" section, this security update is meant to be used with the Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package. You cannot apply this security update to any other editions of Microsoft Visual Studio 2005 Service Pack 1.

Note The Microsoft Download Center update KB numbers for Visual C++ Redistributable packages differ from the SMS, ConfigMgr, WSUS and MU update KB numbers. The full versions of the fixed Visual C++ 2005 and 2008 redistributable packages (KB973544, KB973551, and KB973552) are listed on the Microsoft Download Center only as these are full new versions of the products. The updates listed on SMS, ConfigMgr, WSUS, and MU (KB973923, KB9739234) are updates only for customers who have previously installed vulnerable versions of the Visual C++ redistributable packages. These updates are not the versions on the download center. Microsoft does not recommend customers redistribute any version other than the full versions that can be downloaded from the Microsoft Download Center (KB973544, KB973551, and KB973552).
