CVE-2014-3703

Status Candidate

Overview

OpenStack PackStack 2012.2.1, when the Open vSwitch (OVS) monolithic plug-in is not used, does not properly set the libvirt_vif_driver configuration option when generating the nova.conf configuration, which causes the firewall to be disabled and allows remote attackers to bypass intended access restrictions.

Red Hat Security Advisory 2014-1691-01
Posted Oct 22, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-1691-01 - PackStack is a command-line utility that uses Puppet modules to support rapid deployment of OpenStack on existing servers over an SSH connection. PackStack is suitable for deploying both single node proof-of-concept installations and more complex multi-node installations. It was discovered that the nova.conf configuration generated by PackStack did not correctly set the libvirt_vif_driver configuration option if the Open vSwitch monolithic plug-in was not used. This could result in deployments defaulting to having the firewall disabled unless the nova configuration was manually modified after PackStack was started.
