CVE-2014-3703: Red Hat Packstack

Medium severity, CVSS 5.0. EPSS: 2.2% chance of exploitation in the next 30 days.

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.
