Vulnerability Description MSXML is an application for processing Extensible Stylesheet Language Transformation in an XML file that allows programmers to create high-performance XML-based applications. A remote code execution vulnerability has been reported in Microsoft XML Core Services (MSXML). The vulnerability is due to the way that Microsoft XML Core Services handles nested tags.
