Description of problem:
When a currently unconfigured USB printer is connected to the system,
a popup dialog appears prompting for the selection of a driver. There
is no check for authorization. An unprivileged user should not be
allowed to create a print queue.
Until this problem is corrected, cups-config-daemon should not be run
on any system where security of the printer configuration is a concern.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Turn on or connect a currently unconfigured USB printer.
I fail to see how this is any different from mounting a disk, burning
to a cd or attaching a camera to a computer. Risk is limited and
behavior can be modified by a sysadmin.
When you unmount a disk or unplug a camera, the system goes back to
its previous state. The added print queue, on the other hand,
persists until a system administrator removes it.
Ah, that is a bug.
