Version Summary:Additional technical information to describe the Microsoft Internet Explorer HTMLLayout object processing memory corruption vulnerability is available.
 
 
Description
A vulnerability in Microsoft Internet Explorer could allow an unauthenticated, remote attacker to execute arbitrary code.

The vulnerability is due to improper memory operations performed by Internet Explorer. An attacker could exploit this vulnerability by persuading a user to view a malicious website. An exploit could allow the attacker to execute arbitrary code on the targeted system with the privileges of the targeted user

Functional code that exploits this vulnerability is available as part of the Metasploit framework.

Microsoft has confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
Microsoft Internet Explorer 9 is affected when running on the following supported Microsoft platforms:
  • Windows Vista and x64 Edition SP2
  • Windows Server 2008 for 32-bit and x64-based Systems SP2
  • Windows Server 2008 for Itanium-Based Systems SP2
  • Windows Server 2008 R2 for 32-bit and x64-based Systems SP1
  • Windows 7 for 32-bit and x64-based Systems SP1
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.

Microsoft has resolved the vulnerability by correcting the way the affected software handles objects in memory.

The Cisco Applied Intelligence team has created an Applied Mitigation Bulletin to address vulnerabilities that Microsoft disclosed in the March 2014 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 March 2014.
 
Vendor Announcements
Microsoft has released a security bulletin at the following link: MS14-012
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on a targeted system. If the targeted user holds elevated privileges, the attacker could execute code to cause a complete system compromise.
 
Technical Information
The vulnerability is due to improper handling of HTMLLayout objects in memory by the affected software.

An unauthenticated, remote attacker could exploit this vulnerability by persuading a user to visit a malicious web page that could submit crafted elements to the affected software. When processing the page, the software may reuse the dangling pointer after it has been freed and could trigger a use-after-free condition in certain memory locations. The attacker could use this condition to execute arbitrary code on a targeted system in the context of the user running the browser. If the user holds elevated privileges, the attacker could completely compromise the system.
 
Safeguards
Administrators are advised to apply the appropriate updates.

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

Administrators may consider configuring Internet Explorer to prompt users before running Active Scripting or ActiveX controls by setting the Internet and Local Intranet security zone settings to High. Alternately, administrators could disable Active Scripting and ActiveX controls in these security zones.

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 monitor affected 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.
