Package: core-network
Version: 4.8-1
Severity: critical
Tags: security
Justification: root security hole

This bug was found and reported by asaladin on OFTC #debian. As he has
yet to report a bug, I'm reporting it for him.

Steps to reproduce:
1. Start core-gui as a normal user.
2. Create a host from the toolbar on the left.
3. Start the session using the green button on the toolbar.
4. Double-click on the host

Now you get a root shell. I've tested it by adding a line to /etc/passwd
and by creating a file in /root/.

The bug is most probably in core-network-daemon, as that is the only
part that runs as root. The bug should be exploitable without using the
GUI, but I do not know enough about core-network to try to reproduce it
using the command-line tools.
