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

The vulnerability is due to improper processing of specially crafted Visio files in Microsoft Visio Viewer. An unauthenticated, remote attacker could exploit this vulnerability by sending a specially crafted Visio file to a targeted user and attempting to convince the user to open the file. When processed by Visio Viewer, the crafted file may trigger memory corruption that the attacker could use to execute arbitrary code with the privileges of the user.

Microsoft confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
The following Microsoft products are affected:
  • Microsoft Visio Viewer SP 1 32-bit Edition
  • Microsoft Visio Viewer SP 1 64-bit Edition
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a file or a link to a malicious website and use misleading language or instructions to persuade the user to open the file or follow the provided link.

Microsoft has corrected this vulnerability by modifying the way Microsoft Visio Viewer allocates memory when parsing specially crafted Visio files.

The Cisco Applied Intelligence team has created an Applied Mitigation Bulletin to address vulnerabilities that Microsoft disclosed in the March 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 March 2013

 
Vendor Announcements
Microsoft has released a security bulletin at the following link: MS13-023
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on the targeted system with the privileges of the user. If the user holds administrative privileges, an attacker could completely compromise the targeted system.
 
Technical Information
The vulnerability is due to improper memory operations by the affected software while parsing specially crafted Visio files.

An unauthenticated, remote attacker could exploit this vulnerability by sending a specially crafted Visio file to a targeted user and attempting to convince the user to open the file. When processed by Visio Viewer, the crafted file may trigger memory corruption that the attacker could use to execute arbitrary code with the privileges of the user.
 
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.

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.
