SUMMARY

Microsoft has released an update to Internet Explorer that addresses a potential security issue. The HTML FORM elements support a variety of methods of providing input by using the form, one of which allows the user to specify the name of a file to upload to the site. Subject to a number of constraints, it could be possible for a Web-based program to fill in this field with the name of a desired file to upload it without the user's knowledge when the user submitted the form.

Additional information about this issue is available from the following Microsoft Web site:
