Technical Information

Brief overview of the risk:
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a specially crafted file using WordPad or selects or opens a shortcut file that is on a network or WebDAV share.
Detailed Information on the risk:

A remote code execution vulnerability exists in the way that the Windows Shell and WordPad validate COM object instantiation. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.
