Microsoft Security Bulletin MS13-025 - Important

Vulnerability in Microsoft OneNote Could Allow Information Disclosure

Published: March 12, 2013

Version: 1.0

General Information

Executive Summary

This security update resolves a privately reported vulnerability in Microsoft OneNote. The vulnerability could allow information disclosure if an attacker convinces a user to open a specially crafted OneNote file.

This security update is rated Important for all supported editions of Microsoft OneNote 2010. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerability by modifying how Microsoft OneNote checks the size of a buffer to be allocated. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Recommendation. Customers can configure automatic updating to check online for updates from Microsoft Update by using the Microsoft Update service. Customers who have automatic updating enabled and configured to check online for updates from Microsoft Update typically will not need to take any action because this security update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates from Microsoft Update and install this update manually. For information about specific configuration options in automatic updating in supported editions of Windows XP and Windows Server 2003, see Microsoft Knowledge Base Article 294871. For information about automatic updating in supported editions of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2, see Understanding Windows automatic updating.

For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update at the earliest opportunity using update management software, or by checking for updates using the Microsoft Update service.

FAQ

What is the scope of the vulnerability? 
This is an information disclosure vulnerability.

What causes the vulnerability? 
The vulnerability is caused by a buffer size validation issue that allows an attacker to read arbitrary data in memory.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could discover sensitive information, such as the username and password for configured accounts.

How could an attacker exploit the vulnerability? 
In a web-based attack scenario, an attacker could exploit the vulnerability by convincing a user to open a specially crafted OneNote file.

What is Microsoft OneNote 2010? 
Microsoft OneNote 2010 is a digital notebook that provides people with one place to gather their notes and information, powerful search capability to find what they are looking for quickly, and easy-to-use shared notebooks so that they can manage information overload and work together more effectively.

What systems are primarily at risk from the vulnerability? 
Systems, such as workstations and terminal servers, on which the affected software is installed, are primarily at risk from the vulnerability. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

What does the update do? 
The update addresses the vulnerability by modifying how Microsoft OneNote checks the size of a buffer to be allocated.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.
