  script_tag(name:"insight", value:"A vulnerability was in found in PowerDNS Authoritative Server. The issue
is a memory leak occurring while parsing some malformed records, due to
the fact that some memory is allocated parsing a record and is not
always properly released if the record is not valid. It allows an
authorized user to cause a denial of service by inserting specially
crafted records in a zone under their control, then sending DNS queries
for that zone (CVE-2018-10851).

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 (CVE-2018-14626).");
