CVE-2016-5426 / CVE-2016-5427 
Florian Heinz and Martin Kluge reported that the PowerDNS
Authoritative Server accepts queries with a qname's length larger
than 255 bytes and does not properly handle dot inside labels. A
remote, unauthenticated attacker can take advantage of these flaws
to cause abnormal load on the PowerDNS backend by sending specially
crafted DNS queries, potentially leading to a denial of service.

CVE-2016-6172 
It was reported that a malicious primary DNS server can crash a
secondary PowerDNS server due to improper restriction of zone size
limits. This update adds a feature to limit AXFR sizes in response
to this flaw.");
