Security Fixes

       in CVE-2015-8704. [RT #41396]

       described in CVE-2015-3193.

       socket error occurred while performing a lookup. This flaw is
       disclosed in CVE-2015-8461. [RT#40945]
     * Insufficient testing when parsing a message allowed records with an
       incorrect class to be be accepted, triggering a REQUIRE failure
