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 :

- Multiple elevation of privilege vulnerabilities exist
due to improper handling of session objects. A local
attacker can exploit these, via a specially crafted
application, to hijack the session of another user.
(CVE-2016-3305, CVE-2016-3306)

- An flaw exists in the Windows Kernel API due to improper
enforcement of permissions. A local attacker can exploit
this, via a specially crafted application, to elevate
privileges and thereby disclose potentially sensitive
information. (CVE-2016-3371)

- An elevation of privilege vulnerability exists in the
Windows Kernel API due to improper enforcement of
permissions. A local attacker can exploit this, via a
specially crafted application, to impersonate processes,
interject cross-process communication, or interrupt
system functionality. (CVE-2016-3372)

- An flaw exists in the Windows Kernel API due to
improperly allowing access to sensitive registry
information. A local attacker can exploit this, via a
specially crafted application, to elevate privileges
and thereby gain access to user account information.
(CVE-2016-3373)
