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)

Red Hat would like to thank ISC for reporting this issue. Upstream
acknowledges Tony Finch (University of Cambridge) and Marco Davids (SIDN
Labs) as the original reporters.

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
