Executive Summary

This security update resolves a privately reported vulnerability in the Open 
Data (OData) protocol. The vulnerability could allow denial of service if an 
unauthenticated attacker sends specially crafted HTTP requests to an affected 
site. Firewall best practices and standard default firewall configurations can 
help protect networks from attacks that originate outside the enterprise 
perimeter. Best practices recommend that systems that are connected to the 
Internet have a minimal number of ports exposed.

This security update is rated Important for Microsoft .NET Framework 3.5, 
Microsoft .NET Framework 3.5 Service Pack 1, Microsoft .NET Framework 3.5.1, 
and Microsoft .NET Framework 4. It is also rated Important for Management 
OData IIS Extension when installed on Microsoft Windows Server 2012. 

The security update addresses the vulnerability by turning off the WCF Replace 
function by default.
