Synopsis

The Microsoft .NET Framework install on the remote host is affected by an improper validation vulnerability.

Description

The remote Windows host is running a version of the Microsoft .NET Framework that improperly validates the trust level within the System.Net.Sockets namespace. A remote attacker could exploit this issue by tricking a user into viewing a specially crafted XML file, resulting in information disclosure or partial denial of service.

Solution

Microsoft has released a set of patches for .NET Framework 2.0, 3.5.1, and 4.
