SCA: security update for neutron (GHSA-8q95-jj7p-x93x)

medium Tenable Self-Hosted Container Security Plugin ID 432352

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Live-migrated instances are briefly able to inspect traffic for other instances on the same hypervisor.
 This brief window could be extended indefinitely if the instance's port is set administratively down prior
 to live-migration and kept down after the migration is complete. This is possible due to the Open vSwitch
 integration bridge being connected to the instance during migration. When connected to the integration
 bridge, all traffic for instances using the same Open vSwitch instance would potentially be visible to the
 migrated guest, as the required Open vSwitch VLAN filters are only applied post-migration. Versions of
 openstack-neutron before 13.0.0.0b2, 12.0.3, 11.0.5 are vulnerable. (CVE-2018-14636)
