correctly.

Security Fix(es):

  * A denial of service flaw was found in the way BIND constructed a response
to a query that met certain criteria. A remote attacker could use this flaw
to make named exit unexpectedly with an assertion failure via a specially
crafted DNS request packet. (CVE-2016-2776)

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