1. Problem Description
The OpenLinux package contains a CGI script called rpm_query
that allows a user to obtain a list of all RPM packages installed
on that machine, provided the Apache Web server is running.
This could be used by an intruder to determine what part of the
system to attack.
2. Vulnerable Versions
System Package
