Microsoft OneNote contains a vulnerability that could allow an unauthenticated, remote attacker to access sensitive information on a targeted system. Updates are available.
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.
Microsoft OneNote 2010 SP1 (32-bit and 64-bit editions) is vulnerable.
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.
Microsoft has released a security bulletin at the following link: MS13-025
An unauthenticated, remote attacker could exploit the vulnerability to access sensitive information, including login credentials.
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.
