Microsoft Outlook Information Disclosure Vulnerability
An information disclosure vulnerability exists in Outlook when a message is opened. This vulnerability could potentially result in the disclosure of sensitive information to a malicious site.
To exploit the vulnerability, an attacker would have to send a malicious email to a user and convince the user to open the email. A connection to a remote SMB server could then be automatically initiated, enabling the attacker to brute-force attack the corresponding NTLM challenge and response in order to disclose the corresponding hash password. Depending on the URL contained in the malicious email, Outlook could fall back to initating a web request to a remote server, disclosing the the external IP of the user's system.
The security update addresses the vulnerability by correcting how Outlook processes embedded URLs.
FAQ
I am being offered this update for software that is not specifically indicated as being affected in the Affected Software and Vulnerability Severity Ratings table. Why am I being offered this update?
When updates address vulnerable code that exists in a component that is shared between multiple Microsoft Office products or shared between multiple versions of the same Microsoft Office product, the update is considered to be applicable to all supported products and versions that contain the vulnerable component.
For example, when an update applies to Microsoft Office 2007 products, only Microsoft Office 2007 may be specifically listed in the Affected Software table. However, the update could apply to Microsoft Word 2007, Microsoft Excel 2007, Microsoft Visio 2007, Microsoft Compatibility Pack, Microsoft Excel Viewer, or any other Microsoft Office 2007 product that is not specifically listed in the Affected Software table. Furthermore, when an update applies to Microsoft Office 2010 products, only Microsoft Office 2010 may be specifically listed in the Affected Software table. However, the update could apply to Microsoft Word 2010, Microsoft Excel 2010, Microsoft Visio 2010, Microsoft Visio Viewer, or any other Microsoft Office 2010 product that is not specifically listed in the Affected Software table.
