   An update that fixes 5 vulnerabilities is now available.

Description:


   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.
