Microsoft has released a cumulative patch for Microsoft Outlook Express. This cumulative patch includes updates for the issues that are described in the following Microsoft Knowledge Base article:
328676The patch that this article describes applies to the following versions of Microsoft Outlook Express:

Because of this vulnerability in the MHTML URL Handler, it would be possible to construct a Uniform Resource Locator (URL) that referred to a text file that was stored on the local computer and have that file render as HTML. If the text file contained script, that script would run when the file was accessed. Because the file would reside on the local computer, it would be rendered in the Local Computer Security Zone. Files that are opened in the Local Computer Zone are subject to fewer restrictions than files that are opened in other security zones.
By using this method, an attacker could try to construct a URL and either host it on a Web site or send it by using an e-mail message. In the Web-based scenario, where a user clicked a URL that is hosted on a Web site, an attacker could read or open files that are already present on the local computer. In an e-mail message-based attack, if the user was using Outlook Express 6.0 or Microsoft Outlook 2002 in its default configuration, or Microsoft Outlook 98 or Microsoft Outlook 2000 with the Outlook E-mail Security Update, an attack could not be automated, and the user would still have to click the URL that was sent in the e-mail message. However, if the user was not using Outlook Express 6.0 or Outlook 2002 in its default configuration, or Outlook 98 or 2000 with the Outlook E-mail Security Update, the attacker could cause an attack to trigger automatically without the user having to click the URL in the e-mail message. In both the Web-based and e-mail message-based scenarios, any limitations on the user's privileges would also restrict the capabilities of the attacker's script.
Applying the patch that is described in the following Microsoft Knowledge Base article will help block an attacker from being able to load a file onto a user's computer and prevent the passing of parameters to an executable file.
810847This means that an attacker could only start a program that already existed on the computer (if the attacker was aware of the location of the program) and would not be able to pass parameters to the program for it to run.

MHTML is a standard for exchanging HTML content in e-mail, and, as a result, the MHTML URL Handler function has been implemented in Outlook Express. Internet Explorer can also render MHTML content. However, the MHTML function has not been implemented separately in Internet Explorer - it uses Outlook Express to render the MHTML content.
