It was discovered that consolehelper configuration files
(/etc/security/console.apps/system-config-network*) as shipped in Fedora 8
system-config-network packages allowed any local console user to start
system-config-network configuration program with root privileges by providing
only user password, not administrator password.  This allows any user with local
console access to change network configuration of the host.

Configuration file did not include USER=root directive and tried to include file
config-util, which does not exist on Fedora 8 and is only provided by usermode
package in Fedora 9.  Without USER= specification, consolehelper prompted user
for user password instead of intended root password.
