CVE-2018-10851: An issue has been found in PowerDNS Authoritative
Server allowing an authorized user to cause a memory leak by inserting
a specially crafted record in a zone under their control, then sending
a DNS query for that record. The issue is due to the fact that some
memory is allocated before the parsing and is not always properly
released if the record is malformed. When the PowerDNS Authoritative
Server is run inside the guardian (--guardian), or inside a supervisor
like supervisord or systemd, an out-of-memory crash will lead to an
automatic restart, limiting the impact to a somewhat degraded service.

CVE-2018-14626: An issue has been found in PowerDNS Authoritative
Server allowing a remote user to craft a DNS query that will cause an
answer without DNSSEC records to be inserted into the packet cache and
be returned to clients asking for DNSSEC records, thus hiding the
presence of DNSSEC signatures for a specific qname and qtype. For a
DNSSEC-signed domain, this means that DNSSEC validating clients will
consider the answer to be bogus until it expires from the packet
cache, leading to a denial of service."
