Bug Description

This is in Ubuntu Breezy. I use XFCE as the desktop and network-admin to switch networks betwen home and work. At work, everything is hardwired ethernet, but at home I use a wireless network.

I found that /etc/network/interfaces is world-readable. Since WEP keys are maintained in that file, this is something of a security risk. This file should only be readable by root.

I don't know if this is the normal permissions on this file, or if this is a bug on the part of network-admin, or a GNOME bug (since I used to run GNOME before switching to XFCE). 'dpkg -S' doesn't list an owner for /etc/network/interfaces, so I didn't attach this bug report to a package.
