2018-05 archive
Executive Summary
A denial of service vulnerability exists when .NET and .NET Core improperly process XML documents. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to a .NET (or .NET core) application. The update addresses the vulnerability by correcting how .NET and .NET Core applications handle XML document processing.
