Read Me First

This update resolves the "Malformed Web Form Submission" security vulnerability in FrontPage Server Extensions (FPSE) that ship as part of Internet Information Server (IIS) 4.0. FPSE is a set of programs that run on an IIS Web server, and administrators can use FPSE to manage and develop content for a Web site. The component of FPSE that provides support for the processing of Web forms may process malformed submissions incorrectly. If a malicious user creates a specially malformed Web form and submits it to an affected server, the IIS service could fail. If this occurs, an administrator must restart the service, and any Web sessions that are in progress at the time of an attack are lost. Download now to prevent a malicious user from disrupting the operation of your Web server.

Note This update applies to all languages.

For more information about this vulnerability, please read Microsoft Security Bulletin MS00-100.
