"This update for bind fixes the following issues: CVE-2017-3137
(bsc#1033467): Mistaken assumptions about the ordering of records in
the answer section of a response containing CNAME or DNAME resource
records could have been exploited to cause a denial of service of a
bind server performing recursion. CVE-2017-3136 (bsc#1033466): An
attacker could have constructed a query that would cause a denial of
service of servers configured to use DNS64. CVE-2017-3138
(bsc#1033468): An attacker with access to the BIND control channel
could have caused the server to stop by triggering an assertion
failure. CVE-2016-6170 (bsc#987866): Primary DNS servers could have
caused a denial of service of secondary DNS servers via a large AXFR
response. IXFR servers could have caused a denial of service of IXFR
clients via a large IXFR response. Remote authenticated users could
have caused a denial of service of primary DNS servers via a large
UPDATE message. CVE-2016-2775 (bsc#989528): When lwresd or the named
lwres option were enabled, bind allowed remote attackers to cause a
denial of service (daemon crash) via a long request that uses the
lightweight resolver protocol.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
