Version Summary:Additional technical information to describe the Microsoft Windows Object Linking and Embedding arbitrary code execution vulnerability is available.
 
 
Description
A vulnerability in Microsoft Windows could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.

The vulnerability is due to improper memory operations when handling objects in memory by the affected software. An unauthenticated, remote attacker could exploit this vulnerability by sending an email message to a targeted user and convincing the user to open an attachment that contains a document with crafted Object Linking and Embedding (OLE) objects. Successful exploitation could allow the attacker to execute arbitrary code on the system with the privileges of the user.

Microsoft has confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
The following Microsoft products are affected:
  • Windows XP SP3
  • Windows XP Professional x64 Edition SP2
  • Windows Server 2003 and x64 Edition SP2
  • Windows Server 2003 with SP2 for Itanium-based Systems
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a file to the user and persuade the user to open or execute the file by using misleading language or instructions.

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

The Cisco Applied Intelligence team has created an Applied Mitigation Bulletin to address vulnerabilities that Microsoft disclosed in the September 2013 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 September 2013
 
Vendor Announcements
Microsoft has released a security bulletin at the following link: MS13-070
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on a targeted system with the privileges of the user. If the user holds elevated privileges, the attacker could completely compromise the system.
 
Technical Information
The vulnerability is due to improper parsing of certain Microsoft Office Visio template (VST) files by the affected software.

An unauthenticated, remote attacker could exploit this vulnerability by persuading a user to open a malicious VST file that contains a crafted OLE object. The affected software accepts a length specified in the file and uses the length to provide size information to a memcpy() function. This may trigger a buffer overflow condition, allowing the attacker to execute arbitrary code on the targeted system in the context of the affected process.
 
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 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.
 
Alert History
 
Version 1, September 10, 2013, 5:21 PM: Microsoft Windows contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system. Updates are available.
