<p>An information disclosure vulnerability exists when Internet Explorer improperly handles page content, which could allow an attacker to detect the existence of specific files on the user's system.</p> <p>To exploit the vulnerability, in a web-based attack scenario, an attacker could host a website that is used to attempt to exploit the vulnerability. In addition, compromised websites and websites that accept or host user-provided content could contain specially crafted content that could exploit the vulnerability. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action. For example, an attacker could trick users into clicking a link that takes them to the attacker's site.</p> <p>The security update addresses the vulnerability by helping to ensure that page content is properly validated in Internet Explorer.</p>
