The L3-agent in OpenStack Neutron before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2 allows remote authenticated users to cause a denial of service (IPv4 address attachment outage) by attaching an IPv6 private subnet to a L3 router.
An issue was discovered in OpenStack Neutron 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. 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. All Neutron deployments utilizing neutron-openvswitch-agent are affected.
OpenStack Neutron before 2014.2.4 and 2014.1 before 2014.1.2 allows remote authenticated users to set admin network attributes to default values via unspecified vectors.
Authentication Bypass by Spoofing vulnerability in Neutron Neutron Smart VMS allows Authentication Bypass.This issue affects Neutron Smart VMS: before b1130.1.0.1.
