Synopsis

The version of the .NET Framework installed on the remote host is affected by multiple vulnerabilities.

Description

The remote Windows host is running a version of the Microsoft .NET Framework that is affected by multiple vulnerabilities :

- A denial of service vulnerability exists in the Microsoft .NET Framework due to a recursion flaw that occurs when decrypting XML data. A remote attacker can exploit this, via specially crafted XML data, to degrade the performance of a .NET website. (CVE-2015-1672)

- A privilege escalation vulnerability exists in the Microsoft .NET Framework due to improper handling of objects in memory by .NET's Windows Forms (WinForms) libraries. A remote attacker can exploit this, via a specially crafted partial trust application, to escalate privileges. (CVE-2015-1673)

Solution

Microsoft has released a set of patches for .NET Framework 1.1 SP1, 2.0 SP2, 3.5, 3.5.1, 4.0, 4.5, 4.5.1, and 4.5.2.
