Microsoft Security Bulletin MS12-016 - Critical
Vulnerabilities in .NET Framework and Microsoft Silverlight Could Allow Remote Code Execution (2651026)
Published: Tuesday, February 14, 2012 | Updated: Wednesday, February 15, 2012
Version: 1.2
General Information
Executive Summary
This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in Microsoft .NET Framework and Microsoft Silverlight. The vulnerabilities could allow remote code execution on a client system if a user views a specially crafted web page using a web browser that can run XAML Browser Applications (XBAPs) or Silverlight applications. 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 Microsoft .NET Framework 2.0 Service Pack 2, Microsoft .NET Framework 3.5.1, and Microsoft .NET Framework 4 on all supported editions of Microsoft Windows; and for Microsoft Silverlight 4. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerabilities by correcting the manner in which Microsoft .NET Framework and Microsoft Silverlight use unmanaged objects. 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.
