Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of
Privilege (981957)
Version: 1.0
General Information
Executive Summary
This security update resolves several publicly disclosed vulnerabilities in
the Windows kernel-mode drivers. The most severe of these vulnerabilities
could allow elevation of privilege if an attacker logs on to an affected
system and runs a specially crafted application. An attacker must have valid
logon credentials and be able to log on locally to exploit this vulnerability.
The vulnerability could not be exploited remotely or by anonymous users.
This security update is rated Important for all supported editions of
Microsoft Windows. For more information, see the subsection, Affected and
Non-Affected Software, in this section.

Vulnerability Information
Win32K Reference Count Vulnerability - CVE-2010-2549
An elevation of privilege vulnerability exists due to the way that the Windows
kernel-mode drivers maintain the reference count for an object. An attacker
who successfully exploited this vulnerability could run arbitrary code in
kernel mode. An attacker could then install programs; view, change, or delete
data; or create new accounts with full user rights.
Win32K Keyboard Layout Vulnerability - CVE-2010-2743
An elevation of privilege vulnerability exists due to the way that the Windows
kernel-mode drivers load specific keyboard layouts. An attacker who
successfully exploited this vulnerability could run arbitrary code in kernel
mode. An attacker could then install programs; view, change, or delete data;
or create new accounts with full user rights.
Win32k Window Class Vulnerability - CVE-2010-2744
An elevation of privilege vulnerability exists when the Windows kernel-mode
drivers do not properly validate window class data. An attacker who
successfully exploited this vulnerability could run arbitrary code in kernel
mode. An attacker could then install programs; view, change, or delete data;
or create new accounts with full user rights.
