MS16-155: Security Update for .NET Framework (3205640)

high Nessus Plugin ID 95772

Synopsis

The remote Windows host is affected by an information disclosure vulnerability.

Description

The remote Windows host is missing a security update. It is, therefore, affected by an information disclosure vulnerability in the .NET Framework Data Provider for SQL Server due to improper handling of developer-supplied keys. An unauthenticated, remote attacker can exploit this to disclose sensitive information that should be protected by the Always Encrypted feature. Furthermore, an attacker who can access incorrectly encrypted data could decrypt that data by using an easily guessable key. Misuse of the key can also result in access to data being temporarily lost.

Solution

Microsoft has released a set of patches for Microsoft .NET Framework 4.6.2.
