APAR Error Description / Circumvention

-------------------------------------------------
ISC released CVE-2016-2775, CVE-2016-2776 and CVE-2016-8864.
CVE-2016-2775: A query name which is too long can cause a
segmentation fault in lwresd.
CVE-2016-2776: A defect in the rendering of messages into
packets can cause named to exit with an assertion failure in
buffer.c while constructing a response to a query that meets
certain criteria. This assertion can be triggered even if the
apparent source address isn't allowed to make queries (i.e.
doesn't match 'allow-query').
CVE-2016-8864: A defect in BIND's handling of responses
containing a DNAME answer can cause a resolver to exit after
encountering an assertion failure in db.c or resolver.c.

CORRECTION FOR APAR 'SE66025' :
