The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities in the .NET Framework :
A denial of service vulnerability exists due to improper handling of certain Extensible Stylesheet Language Transformations (XSLT). A remote attacker can exploit this, via specially crafted XSLT inserted into a client-side web part, to cause the server to recursively compile XSLT transforms, resulting in significant degradation of server performance. (CVE-2016-0033)
An information disclosure vulnerability exists in Windows Forms due to improper handling of icon data.
A remote attacker can exploit this, by uploading a specially crafted icon, to capture information that is returned within the icon’s data. (CVE-2016-0047)
