<p>An information disclosure vulnerability exists when Office renders Rich Text Format (RTF) email messages containing OLE objects when a message is opened or previewed. This vulnerability could potentially result in the disclosure of sensitive information to a malicious site.</p> <p>To exploit the vulnerability, an attacker would have to send an RTF-formatted email to a user and convince the user to open or preview 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.</p> <p>The security update addresses the vulnerability by correcting how Office processes OLE objects.</p>
