USN-3195-1: Nova-LXD vulnerability

Releases

• Ubuntu 16.04 ESM

Packages

• 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

• python-nova-lxd - 13.2.0-0ubuntu1.16.04.1

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.
