handle TKEY queries. A remote attacker can take advantage of this flaw
to mount a denial of service via a specially crafted query triggering
an assertion failure and causing BIND to exit.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
