An attacker who is able to send and receive messages to an authoritative
DNS server and who has knowledge of a valid TSIG key name may be able to
circumvent TSIG authentication of AXFR requests via a carefully constructed
request packet. A server that relies solely on TSIG keys for protection
with no other ACL protection could be manipulated into: providing an AXFR
of a zone to an unauthorized recipient or accepting bogus NOTIFY packets.
Affects BIND 9.4.0->9.8.8, 9.9.0->9.9.10-P1, 9.10.0->9.10.5-P1,
9.11.0->9.11.1-P1, 9.9.3-S1->9.9.10-S2, 9.10.5-S1->9.10.5-S2.
