than 255 bytes (CVE-2016-5426). PowerDNS Authoritative Server does not
properly handle dot inside labels (CVE-2016-5427). These issues allow a
remote, unauthenticated attacker to cause an abnormal load on the PowerDNS
backend by sending crafted DNS queries, which might result in a partial
denial of service if the backend becomes overloaded.

It was found that PowerDNS does not implement reasonable restrictions for
zone sizes. This allows an explicitly configured primary DNS server for a
zone to crash a secondary DNS server, affecting service of other zones
hosted on the same secondary server (CVE-2016-6172).");
