Impact: Visiting a malicious website may result in the disclosure of sensitive information
Description: WebKit allows a page to navigate the subframes of any other page. Visiting a maliciously crafted web page could trigger a cross-site scripting attack, which may lead to the disclosure of sensitive information. This update addresses the issue by implementing a stricter frame navigation policy. (This issue is addressed for Mac OS X in Security Update 2007-009.)
