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)
