An update that solves 5 vulnerabilities and has one errata

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.

 

One additional non-security bug was fixed:

 

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