1. Summary:
An update for bind is now available for Red Hat Enterprise Linux 7.2
Extended Update Support.
Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux ComputeNode EUS (v. 7.2) - noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.2) - x86_64
Red Hat Enterprise Linux Server EUS (v. 7.2) - noarch, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.2) - ppc64, ppc64le, s390x, x86_64
3. Description:
The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
library (routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating correctly.
Security Fix(es):
* A denial of service flaw was found in the way BIND handled responses
containing a DNAME answer. A remote attacker could use this flaw to make
named exit unexpectedly with an assertion failure via a specially crafted
DNS response. (CVE-2016-8864)
* A denial of service flaw was found in the way BIND processed a response
to an ANY query. A remote attacker could use this flaw to make named exit
unexpectedly with an assertion failure via a specially crafted DNS
response. (CVE-2016-9131)
* A denial of service flaw was found in the way BIND handled a query
response containing inconsistent DNSSEC information. A remote attacker
could use this flaw to make named exit unexpectedly with an assertion
failure via a specially crafted DNS response. (CVE-2016-9147)
* A denial of service flaw was found in the way BIND handled an
unusually-formed DS record response. A remote attacker could use this flaw
to make named exit unexpectedly with an assertion failure via a specially
crafted DNS response. (CVE-2016-9444)
* A denial of service flaw was found in the way BIND handled a query
response containing CNAME or DNAME resource records in an unusual order. A
remote attacker could use this flaw to make named exit unexpectedly with an
assertion failure via a specially crafted DNS response. (CVE-2017-3137)
Red Hat would like to thank ISC for reporting these issues. Upstream
acknowledges Tony Finch (University of Cambridge) and Marco Davids (SIDN
Labs) as the original reporters of CVE-2016-8864.
Bug Fix(es):
* ICANN is planning to perform a Root Zone DNSSEC Key Signing Key (KSK)
rollover during October 2017. Maintaining an up-to-date KSK is essential
for ensuring that validating DNS resolvers continue to function following
the rollover. (BZ#1459648)
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing the update, the BIND daemon (named) will be restarted
automatically.
5. Bugs fixed (https://bugzilla.redhat.com/):
1389652 - CVE-2016-8864 bind: assertion failure while handling responses containing a DNAME answer
1411348 - CVE-2016-9131 bind: assertion failure while processing response to an ANY query
1411367 - CVE-2016-9147 bind: assertion failure while handling a query response containing inconsistent DNSSEC information
1411377 - CVE-2016-9444 bind: assertion failure while handling an unusually-formed DS record response
1441133 - CVE-2017-3137 bind: Processing a response containing CNAME or DNAME with unusual order can crash resolver
