1. Problem Description

         Docview provides the SCO Linux System Administration Guide,
         available in browser HTML format. 

         Due to a misconfiguration of the apache server, anonymous 
         remote users are able to craft a URL in such a way as to 
         view any publicly readable file.

         The Common Vulnerabilities and Exposures (CVE) project has assigned
         the name CAN-2003-0658 to this issue. This is a candidate for
         inclusion in the CVE list (http://cve.mitre.org), which standardizes
         names for security problems.

2. Vulnerable Supported Versions
