Microsoft Security Bulletin MS11-038 - Critical
Vulnerability in OLE Automation Could Allow Remote Code Execution (2476490)
Published: June 14, 2011
Version: 1.0
General Information
Executive Summary
This security update resolves a privately reported vulnerability in Microsoft Windows Object Linking and Embedding (OLE) Automation. The vulnerability could allow remote code execution if a user visits a Web site containing a specially crafted Windows Metafile (WMF) image. In all cases, however, an attacker would have no way to force users to visit such a Web site. Instead, an attacker would have to convince users to visit a malicious Web site, typically by getting them to click a link in an e-mail message or Instant Messenger request.
This security update is rated Critical for all supported versions of Microsoft Windows. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerability by correcting the manner in which OLE Automation parses WMF files. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
Recommendation. The majority of customers have automatic updating enabled and will not need to take any action because this security update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871.
For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update immediately using update management software, or by checking for updates using the Microsoft Update service.

OLE Automation Underflow Vulnerability - CVE-2011-0658
A remote code execution vulnerability exists in Object Linking and Embedding (OLE) Automation. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. If a user is logged on with administrative user rights, an attacker could take complete control of the 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.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2011-0658.
Mitigating Factors for OLE Automation Underflow Vulnerability - CVE-2011-0658
Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:
