1. Summary:

An update for openstack-neutron is now available for Red Hat OpenStack
Platform 16.1 (Train).

3. Description:

OpenStack Networking (neutron) is a virtual network service for OpenStack.

configure virtual servers, OpenStack Networking provides an API to
dynamically request and configure virtual networks. These networks connect
'interfaces' from other OpenStack services (e.g. virtual NICs from Compute
VMs). The OpenStack Networking API supports extensions to provide advanced
network capabilities (e.g. QoS, ACLs, network monitoring, etc.)

Security Fix(es):

* Routes middleware memory leak for nonexistent controllers
(CVE-2021-40797)
