CVE-2018-16852

Samba from version 4.9.0 and before version 4.9.3 is vulnerable to a NULL
pointer de-reference. During the processing of an DNS zone in the DNS
management DCE/RPC server, the internal DNS server or the Samba DLZ plugin
for BIND9, if the DSPROPERTY_ZONE_MASTER_SERVERS property or
DSPROPERTY_ZONE_SCAVENGING_SERVERS property is set, the server will follow
a NULL pointer and terminate. There is no further vulnerability associated
with this issue, merely a denial of service.
