MS16-019: Security Update for .NET Framework to Address Denial of Service (3137893)

high Nessus Plugin ID 88651

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

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)

Solution

Microsoft has released a set of patches for .NET framework 2.0 SP2, 3.5, 3.5.1, 4, 4.5.1, 4.5.2, 4.6, and 4.6.1.
