Some vulnerabilities have been reported in Microsoft Outlook Express and Windows Mail, which can be exploited by malicious people to disclose sensitive information and compromise a user's system.

1) An error in Windows Mail within the handling of UNC navigation requests can be exploited to execute arbitrary code via a local file or UNC path when a user clicks on a link in a specially crafted email message.

2) An error in the MHTML protocol handler when returning MHTML content can be exploited to read data from another security zone or domain in Internet Explorer when a user visits a specially crafted web page.

3) An error exists in the MHTML protocol handler when passing Content-Disposition notifications back to Internet Explorer. This can be exploited to bypass the file download dialog box and to read data from another Internet Explorer domain when a user visits a specially crafted web page.
