Description Florian Weimer 2015-07-21 14:31:27 UTC 
It was discovered that the Designate component in OpenStack would enter
an infinite loop when processing an internal zone file transfer if a
managed DNS zone included a resource record set whose size exceeded the
limitations of the DNS protocol, leading to a denial of service.  Only
authenticated users with access to the Designate component can add such
resource record sets.
