Descriptions

OpenStack Neutron before 2014.1.4 and 2014.2.x before 2014.2.1 allows remote authenticated users to cause a denial of service (crash) via a crafted dns_nameservers value in the DNS configuration.

OpenStack Neutron anterior a 2014.1.4 y 2014.2.x anterior a 2014.2.1 permite a usuarios remotos autenticados causar una denegación de servicio (caída) a través de un valor dns_nameservers manipulado en la configuración DNS.

A denial of service flaw was found in the way neutron handled the 'dns_nameservers' parameter. By providing specially crafted 'dns_nameservers' values, an authenticated user could use this flaw to crash the neutron service.
