I'm not quite sure how this is different than being able to collide with another IP address on the network. Both will allow a guest user to possibly cause a network outage.
Besides, the guest user requires physical access to be used. If you have physical access, you can most likely unplug the network cable and plug in into a different laptop and do the same thing. Network-manager should probably gain an additional user right to change the mac address in any case, so users who are on the console but not in the admin group wouldn't be able to alter the system's mac address. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1055068 Title: Guest user can use arbitrary MAC addresses To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1055068/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
