Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.04 - Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Bind.

Software Description: - bind9: Internet Domain Name Server

Details:

It was discovered that the resolver in Bind made incorrect assumptions about ordering when processing responses containing a CNAME or DNAME. An attacker could use this cause a denial of service. (CVE-2017-3137)

Oleg Gorokhov discovered that in some situations, Bind did not properly handle DNS64 queries. An attacker could use this to cause a denial of service. (CVE-2017-3136)

Mike Lalumiere discovered that in some situations, Bind did not properly handle invalid operations requested via its control channel. An attacker with access to the control channel could cause a denial of service. (CVE-2017-3138)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 17.04:
bind9 1:9.10.3.dfsg.P4-10.1ubuntu5

Ubuntu 16.10:
bind9 1:9.10.3.dfsg.P4-10.1ubuntu1.6

Ubuntu 16.04 LTS:
bind9 1:9.10.3.dfsg.P4-8ubuntu1.6

Ubuntu 14.04 LTS:
bind9 1:9.9.5.dfsg-3ubuntu0.14

Ubuntu 12.04 LTS:
bind9 1:9.8.1.dfsg.P1-4ubuntu0.22

In general, a standard system update will make all the necessary changes.
