Version Summary:Microsoft Windows contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system. Updates are available.
 
 
Description
Microsoft Windows contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code.

The vulnerability is due to improper handling of the DirectPlay protocol by the DirectX component of the affected software. An unauthenticated, remote attacker could exploit this vulnerability by persuading a user to open a crafted document. A successful exploit could allow the attacker to execute arbitrary code on the system with the privileges of the user. If the user holds administrative privileges, the attacker could completely compromise the system.

Microsoft has confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
The following Microsoft products are affected:

DirectX 9.0 when running on
  • Windows XP SP3
  • Windows XP Professional x64 Edition SP2
DirectX 10.0 when running on
  • Windows Server 2003 SP2
  • Windows Server 2003 SP2 for Itanium-based Systems
  • Windows Server 2008 for Itanium-based Systems SP2.0
  • Windows Vista SP2
  • Windows Vista x64 Edition SP2
  • Windows Server 2008 (32-bit, 64-bit and Itanium) Systems SP2
DirectX 11.0 when running on

IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site or provide a file using an e-mail message or other means and use misleading language or instructions to persuade the user to follow the provided link or open the malicious file.

Microsoft has corrected this vulnerability by modifying the way DirectX parses crafted DirectPlay data.

The Cisco Applied Intelligence team has created an Applied Mitigation Bulletin to address vulnerabilities that Microsoft disclosed in the December 2012 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 December 2012
 
Vendor Announcements

Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on the system with the privileges of the user. If the user holds administrative privileges, the attacker could completely compromise the system.
 
Technical Information
The vulnerability is due to improper memory operations performed by the DirectX component of the Windows operating system when handling the DirectPlay protocol.

An unauthenticated, remote attacker could exploit this vulnerability by persuading a user to open a crafted document that contains malicious embedded content. When DirectX processes the malicious content, a heap overflow memory error condition may occur that the attacker could use to execute arbitrary code on the system with the privileges of the user. If the user holds administrative privileges, the attacker could completely compromise the system.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Users are advised not to open e-mail messages from suspicious or unrecognized sources. If users cannot verify that links or attachments included in e-mail messages are safe, they are advised not to open them.

Users are advised not to visit websites or follow links that have suspicious characteristics or cannot be verified as safe.

Administrators may consider applying the Microsoft Office File Block policy to prevent the opening of Office 2003 and earlier documents from suspicious or unrecognized sources.

Administrators may consider disabling ActiveX controls in Microsoft Office 2007 and Microsoft Office 2010.

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

Administrators are advised to use an unprivileged account when browsing the Internet.

Administrators are advised to monitor critical systems.
 
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 Microsoft Update service. Microsoft Windows Server Update Services (WSUS), Systems Management Server, and System Center Configuration Manager can assist administrators in deploying software updates.
