=====================================================================

1. Summary:

An update for bind is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact

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 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)

Red Hat would like to thank ISC for reporting these issues.

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/):

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
