Version Summary:Microsoft OneNote contains a vulnerability that could allow an unauthenticated, remote attacker to access sensitive information on a targeted system. Updates are available.
 
 
Description
Microsoft OneNote contains a vulnerability that could allow an unauthenticated, remote attacker to access sensitive information.

The vulnerability is due to improper memory operations performed by the affected software when handling crafted OneNote (.ONE) files. An unauthenticated, remote attacker could exploit the vulnerability by providing a malicious .ONE file to a user and persuading the user to open the file. A successful exploit could allow the attacker to access sensitive information, including login credentials.

Microsoft has confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
Microsoft OneNote 2010 SP1 (32-bit and 64-bit editions) is vulnerable.
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a malicious file to a user via e-mail, instant messaging, or other means, and use misleading language or instructions to persuade the user to open the provided file.

Microsoft has corrected the vulnerability by modifying how OneNote performs validations of memory buffer allocation.

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: MS13-025
 
Impact
An unauthenticated, remote attacker could exploit the vulnerability to access sensitive information, including login credentials.
 
Technical Information
The vulnerability exists because the affected software performs insufficient validation of memory buffer allocations when parsing crafted .ONE files.

An unauthenticated, remote attacker could exploit the vulnerability by providing a crafted .ONE file to a user and persuading the user to open the provided file. When the affected software processes the malicious file, a buffer allocation error could allow the attacker to view arbitrary data in memory. A successful exploit could allow the attacker to access sensitive information, including login credentials.
 
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 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.
