Version Summary:

Microsoft Windows contains a vulnerability that could allow a local attacker to execute code with elevated privileges.  Updates are available.

 
 
Description

Microsoft Windows contains a vulnerability that could allow a local attacker to gain elevated privileges on the system.

This vulnerability exists due to improper validation of input passed from usermode applications to the kernel Graphics Device Interface (GDI) component.  A local attacker could exploit this vulnerability by executing a program that is designed to submit malicious input to the kernel.  If successful, the attacker could execute arbitrary code in the elevated security context of the Windows Kernel, granting the attacker escalated privileges.

Microsoft has confirmed this vulnerability in a security bulletin and released software updates.

 
Warning Indicators

The following Microsoft systems are affected:

  • Windows 2000 SP4 and prior
  • Windows XP SP3 and prior
  • Windows XP Professional x64 Edition SP2 and prior
  • Windows Server 2003 SP2 and prior
  • Windows Server 2003 x64 Edition SP2 and prior
  • Windows Server 2003 for Itanium-based Systems SP2 and prior
  • Windows Vista SP2 and prior
  • Windows Vista x64 Edition SP2 and prior
  • Windows Server 2008 for 32-bit Systems SP2 and prior
  • Windows Server 2008 for x64-based Systems SP2 and prior
  • Windows Server 2008 for Itanium-based Systems SP2 and prior
 
IntelliShield Analysis

An attacker must log in locally to the system in order to exploit this vulnerability.  The access requirement may limit the source of potential exploits to current users of affected systems.  An exploit could allow the attacker to gain elevated privileges on the system, possibly resulting in a complete compromise.

The Cisco Applied Intelligence team has created an Applied Mitigation Bulletin to address vulnerabilities that Microsoft disclosed in the November 2009 security bulletin release. This Cisco bulletin, which assists administrators in identifying or mitigating these vulnerabilities using Cisco devices, is available at the following link: Cisco Applied Mitigation Bulletin: Microsoft Security Bulletin Release for November 2009

 
Vendor Announcements

Microsoft has released a security bulletin at the following link: MS09-065

 
Impact

A local attacker could exploit this vulnerability to execute arbitrary code with the privileges of the kernel, allowing the attacker to gain elevated privileges.

 
Technical Information

This vulnerability exists due to improper validation of input passed from usermode applications to the kernel GDI component.  A local attacker could exploit this vulnerability by running an application that is designed to send malicious input to the Windows Kernel.  The processing of the malicious input could cause an error condition that could allow the attacker to execute arbitrary code in the elevated security context of the kernel.

 
Safeguards

Administrators are advised to apply the available software updates.

Administrators are advised to only grant local system access to trusted users.

Administrators are advised to monitor critical systems.

Administrators may consider using the Microsoft Baseline Security Analyzer (MBSA) scan tool to identify common security misconfigurations and missing security updates on system endpoints.

 
Patches/Software

Microsoft customers can obtain updates directly by using the links in the security bulletin. These updates are also distributed by Windows automatic update features and available on the Windows Update website. Microsoft Windows Server Update Services (WSUS), Systems Management Server, and System Center Configuration Manager can assist administrators in deploying software updates.
