nova-lxd vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

Nova-LXD could allow unintended access to LXD instances over the network.

Software Description:
- nova-lxd: Openstack Compute - LXD container hypervisor support

Details:

James Page discovered that Nova-LXD incorrectly set up virtual network devices
when creating LXD instances. This could result in an unintended firewall
configuration.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:

In general, a standard system update will make all the necessary changes for
new instances. However, existing instances will still be affected and must be
manually updated.
