This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

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 :

- An information disclosure vulnerability exists in the
Windows kernel that allows a local attacker, via a
specially crafted application, to bypass the Address
Space Layout Randomization (ASLR) feature and retrieve
the memory address of a kernel object. (CVE-2016-7214)

- Multiple elevation of privilege vulnerabilities exist in
the Windows kernel-mode driver due to improper handling
of objects in memory. A local attacker can exploit
these, via a specially crafted application, to execute
arbitrary code in kernel mode. (CVE-2016-7215,
CVE-2016-7246, CVE-2016-7255)

- An information disclosure vulnerability exists in the
bowser.sys kernel-mode driver due to improper handling
objects in memory. A local attacker can exploit this,
via a specially crafted application, to disclose
sensitive information. (CVE-2016-7218)
