OpenStack Neutron before 2014.2.4 (juno) and 2015.1.x before 2015.1.1 (kilo), when using the IPTables firewall driver, allows remote authenticated users to cause a denial of service (L2 agent crash) by adding an address pair that is rejected by the ipset tool.

Security readout for executives and security teams

This issue affects older OpenStack Neutron deployments using the IPTables firewall driver. An authenticated user could submit an allowed address pair that causes the Neutron L2 agent to crash, creating a denial-of-service condition for networking services. Exposure is most likely in legacy OpenStack Neutron environments before 2014.2.4 Juno or 2015.1.1 Kilo that use the IPTables firewall driver and allow authenticated users to configure allowed address pairs. Prioritize remediation for any production OpenStack cloud still running affected legacy Neutron releases. Business impact is service availability, not confirmed data theft. Urgency is higher for multi-tenant clouds where authenticated users can change networking settings. Mitigation focus: Upgrade affected Neutron Juno deployments to 2014.2.4 or later.; Upgrade affected Neutron Kilo deployments to 2015.1.1 or later.; Review OpenStack and distribution vendor advisories for supported fixes..
