MS11-011: Vulnerabilities in Windows Kernel Could Allow Elevation of Privilege (2393802)

This script is Copyright (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

The Windows kernel is affected by several vulnerabilities that could
allow escalation of privileges.

Description :

The remote Windows host is running a version of the Windows kernel
that is affected by one or more of the following vulnerabilities :

- A buffer overflow in the 'GreEnableEUDC()' function can
be triggered using specially crafted end-user-defined
characters (EUDC) registry key values. (CVE-2010-4398)

- An integer truncation vulnerability exists due to the
failure of the Windows kernel to validate user-supplied
data before allocating memory. (CVE-2011-0045)

An attacker with local access to the affected system can exploit these
issues to execute arbitrary code in kernel mode and take complete
control of the affected system.
