An attacker who successfully exploited this vulnerability could obtain information to further compromise 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.

For example, an attacker could trick a user into clicking a link that takes the user to the attacker's site.</p> <p>The security update addresses the vulnerability by modifying how Microsoft browsers handle objects in memory.</p>
