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

Synopsis :

A multimedia application framework installed on the remote Windows
host is affected by multiple vulnerabilities.

Description :

The version of Microsoft Silverlight installed on the remote Windows
host is affected by the following vulnerabilities :

- Multiple information disclosure vulnerabilities exist
due to a failure to properly handle objects in memory.
An attacker can exploit these issues, via crafted
Silverlight content, to more reliably predict pointer
values and thus degrade the effectiveness of the Address
Space Layout Randomization (ASLR) security feature,
allowing the system to be further compromised.
(CVE-2015-6114, CVE-2015-6165)

- A remote code execution vulnerability exists due to
incorrect handling of certain open and close requests,
which result in read and write access violations. A
remote attacker can exploit this vulnerability, via a
specially crafted Silverlight application, to gain
privileges and take complete control of the affected
host. (CVE-2015-6166)
