[Bug 1386361] [NEW] network-manager-openvpn leaks while connecting

 

Public bug reported:

Network-manager-openvpn leaks while connecting. Maybe that is intended
behavior when activating a VPN-connection manually but it also leaks
when "Automatically connect to VPN when using this connection" is
checked.

Verfied the following way:
1. Set up a VPN that connects via UDP (verify it).
2. Configure a Wifi network that blocks UDP, check "Automatically connect to VPN..." and preselect your special VPN.
3. Connect to that newly configured Wifi network.
4. Browse the internet.

Another way:
1. Type "traceroute ubuntu.com" into a terminal but don't press enter.
2. Start the Wifi network that uses the "Automatically connect... VPN..." feature.
3. Go back to the terminal press enter.
4. After the VPN has connected repeat the command.
5. Compare the first hop of the traceroute results.

I consider this a security bug since it endangers users relying on a
working/leak-free VPN.
