Executive Summary

This security update is rated Important for Microsoft Office SharePoint Server 2010 and Microsoft SharePoint Foundation 2010. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerabilities by correcting the way that Microsoft SharePoint validates and sanitizes user input.
