Synopsis :

The remote openSUSE host is missing a security update.

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.

One additional non-security bug was fixed :

The default umask was changed to 077. (bsc#1020983)

This update was imported from the SUSE:SLE-12-SP1:Update update
