Detail

Revision Note: V1.3 (July 10, 2012): Microsoft revised this bulletin to communicate a minor detection change for KB2572073 for Microsoft .NET Framework 2.0 Service Pack 2 to correct an offering issue. There were no changes to the security update files. Customers who have already successfully updated their systems do not need to take any action.

Summary: This security update resolves a privately reported vulnerability in Microsoft .NET Framework and Microsoft Silverlight. The vulnerability 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. The vulnerability could also allow remote code execution on a server system running IIS, if that server allows processing ASP.NET pages and an attacker succeeds in uploading a specially crafted ASP.NET page to that server and then executes the page, as could be the case in a Web hosting scenario. This vulnerability could also be used by Windows .NET applications to bypass Code Access Security (CAS) restrictions.
