CVE link in the References section.

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.

A denial of service flaw was found in the way BIND processed certain
malformed Address Prefix List (APL) records. A remote, authenticated
attacker could use this flaw to cause named to crash. (CVE-2015-8704)

Red Hat would like to thank ISC for reporting this issue.

All bind97 users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. After
installing the update, the BIND daemon (named) will be restarted
automatically."
