MS15-101: Vulnerabilities in .NET Framework Could Allow Elevation of Privilege (3089662)

This script is Copyright (C) 2015-2017 Tenable Network Security, Inc.


Synopsis :

The version of the .NET Framework installed on 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 Microsoft .NET
Framework :

- An elevation of privilege vulnerability exists due to
improper validation of the number of objects in memory
before they are copied into an array. A remote,
unauthenticated attacker can exploit this to bypass Code
Access Security (CAS) restrictions by convincing a user
to run an untrusted .NET application or to visit a
website containing a malicious XAML browser application.
(CVE-2015-2504)

- A denial of service vulnerability exists due to improper
handling of specially crafted requests to an ASP .NET
server. A remote, unauthenticated attacker can exploit
this to degrade performance. (CVE-2015-2526)

3.5.1, 4, 4.5, 4.5.1, 4.5.2, and 4.6.
