An issue has been found in PowerDNS Authoritative Server allowing an
authorized user to cause the server to exit by inserting a crafted
record in a MASTER type zone under their control. The issue is due
to the fact that the Authoritative Server will exit when it runs into a
parsing error while looking up the NS/A/AAAA records it is about to
use for an outgoing notify.

This issue has been assigned CVE-2019-10162.

PowerDNS Authoritative up to and including 4.1.9 is affected.
Please note that at the time of writing, PowerDNS Authoritative 3.4 and
below are no longer supported, as described in

reporting this issue!
