Introduction

This update resolves a vulnerability in the Microsoft .NET Framework that could allow denial of service if an attacker sends a few specially crafted requests to an affected .NET-enabled website. By default, ASP.NET is not installed when the .NET Framework is installed on any supported edition of Windows. To be affected by the vulnerability, customers must manually install and enable ASP.NET by registering it with Internet Information Services (IIS).
