Security Update, July 17, 2000






Read Me First

This update resolves two security vulnerabilities in Internet Information Server (IIS) 4.0, the "Absent Directory Browser Argument" vulnerability and the "File Fragment Reading via .HTR" vulnerability. Installing this update will prevent a malicious user from exploiting these vulnerabilities to slow performance on an affected Web server or, under very specific conditions, obtain the source code of certain types of files on a Web server. The referenced .HTR files are scripts that Windows NT® users can employ to change passwords, and that administrators can use to perform a variety of password administration functions. Neither of these vulnerabilities allows data to be changed, added, or deleted on the server, nor do they allow administrative control over the affected computer.

For more information on this vulnerability, please visit Microsoft Security Bulletin MS00-044.

Note This update also resolves the vulnerabilities addressed in Microsoft Security Bulletin MS00-031.
