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.
