Microsoft Security Bulletin MS09-060 - Critical

Vulnerabilities in Microsoft Active Template Library (ATL) ActiveX Controls for 
Microsoft Office Could Allow Remote Code Execution (973965)

Published: October 13, 2009

Version: 1.0

General Information

Executive Summary

  This security update resolves several privately reported vulnerabilities in 
  ActiveX Controls for Microsoft that were compiled with a vulnerable version 
  of Microsoft Active Template Library (ATL). The vulnerabilities could allow 
  remote code execution if a user loaded a specially crafted component or 
  control. 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.

  This security update is rated Critical for all supported editions of Microsoft 
  Outlook 2002, Microsoft Office Outlook 2003, Microsoft Office Outlook 2007, 
  Microsoft Visio 2002 Viewer, Microsoft Office Visio 2003 Viewer, and Microsoft 
  Office Visio Viewer 2007.

  The security update addresses the vulnerabilities by correcting the manner in 
  which ATL handles the instantiation of objects from data streams, providing 
  updated versions of the affected components and controls built using 
  corrected ATL headers. 

  Recommendation. Microsoft recommends that customers apply the update 
  immediately.

  Known Issues. Microsoft Knowledge Base Article 973965 documents the currently 
  known issues that customers may experience when installing this security 
  update. The article also documents recommended solutions for these issues. 
  When currently known issues and recommended solutions pertain only to 
  specific releases of this software, this article provides links to further 
  articles.

Affected Software

  Microsoft Outlook 2002 Service Pack 3

  Microsoft Office Outlook 2003 Service Pack 3

  Microsoft Office Outlook 2007 Service Pack 1 and Microsoft Office Outlook 
  2002 Service Pack 2

  Visio 2002 Viewer

  Visio 2003 Viewer

  Visio Viewer 2007, Visio Viewer 2007 Service Pack 1, and Visio Viewer 2007 
  Service Pack 2

Vulnerability Information

ATL Uninitialized Object Vulnerability - CVE-2009-0901

  A remote code execution vulnerability exists in the Microsoft Active Template 
  Library (ATL) due to an issue in the ATL headers that could allow an attacker 
  to force VariantClear to be called on a VARIANT that has not been correctly 
  initialized. Because of this, the attacker can control what happens when 
  VariantClear is called during handling of an error by supplying a corrupt 
  stream. This vulnerability only directly affects systems with components and 
  controls installed that were built using Visual Studio ATL. This issue could 
  allow a remote, unauthenticated user to perform remote code execution on an 
  affected system. An attacker could exploit the vulnerability by constructing 
  a specially crafted Web page. When a user views the Web page, the 
  vulnerability could allow remote code execution.
