How to fix?

Upgrade neutron to version 11.0.7, 12.0.6, 13.0.3 or higher.

Overview

neutron is an OpenStack project to provide “network connectivity as a service” between interface devices (e.g., vNICs) managed by other OpenStack services (e.g., nova). It implements the Neutron API.

Affected versions of this package are vulnerable to Improper Access Control. By creating two security groups with separate/overlapping port ranges, an authenticated user may prevent neutron from being able to configure networks on any compute nodes where those security groups are present, because of an Open vSwitch (OVS) firewall KeyError.
