Microsoft Security Bulletin MS11-025 - Important
Vulnerability in Microsoft Foundation Class (MFC) Library Could Allow Remote 
Code Execution (2500212)
Version: 1.0

General Information

Executive Summary

This security update resolves a publicly disclosed vulnerability in certain 
applications built using the Microsoft Foundation Class (MFC) Library. The 
vulnerability could allow remote code execution if a user opens a legitimate 
file associated with such an affected application, and the file is located in 
the same network folder as a specially crafted library file. For an attack to 
be successful, a user must visit an untrusted remote file system location or 
WebDAV share and open a document from this location that is then loaded by the 
affected application.

This security update is rated Important for all supported editions of Microsoft 
Visual Studio and Microsoft Visual C++ Redistributable Package. For more 
information, see the subsection, Affected and Non-Affected Software, in this 
section.

Affected Software

Microsoft Visual Studio .NET 2003 Service Pack 1
Microsoft Visual Studio 2005 Service Pack 1
Microsoft Visual Studio 2008 Service Pack 1
Microsoft Visual Studio 2010
Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package
Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package
Microsoft Visual C++ 2010 Redistributable Package

Vulnerability Information

MFC Insecure Library Loading Vulnerability - CVE-2010-3190

A remote code execution vulnerability exists in the way that certain 
applications built Microsoft Foundation Classes (MFC) handle the loading of 
DLL files. 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 impacted than users who operate with administrative user 
rights.
