Cause

Have applied only the hotfix KB 979445 without applying KB 983444

Resolution

Apply hotfix KB 983444, this resolves the issue

More Information

Here is the supporting documentation from the FAQ of the technet site http://www.microsoft.com/technet/security/bulletin/ms10-039.mspx  :

In what configurations will I need to apply the different updates?

You will need to apply one or both updates, depending on which SharePoint product is installed on your system. For systems with only Microsoft Windows SharePoint Services 3.0 installed, you will need to apply the KB983444 update. For systems with Microsoft Office SharePoint Server 2007 installed, you will need to apply both the KB979445 and KB983444 updates. There is no configuration where you can only have Microsoft Office SharePoint Server 2007 and not Microsoft Windows SharePoint Services 3.0.

Microsoft Internal Support Information
