MS10-077 - Critical: Vulnerability in .NET Framework Could Allow Remote Code Execution (2160841) - Version:1.2

Severity Rating: Critical - Revision Note: V1.2 (October 26, 2010): Revised this bulletin to announce a detection change to fix an installation issue. This is a detection change only. There were no changes to the security update. Customers who have already installed the update successfully do not need to reinstall.

Summary: This security update resolves a privately reported vulnerability in Microsoft .NET Framework. 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). 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.[/quote6
