APAR Error Description / Circumvention

-------------------------------------------------
ISC released CVE-2017-3142 and CVE-2017-3143.
CVE-2017-3142: 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: 1)providing an AXFR of a zone to an unauthorized
recipient; 2)accepting bogus NOTIFY packets.
CVE-2017-3143: 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 for the zone and service being targeted
may be able to manipulate BIND into accepting an unauthorized
dynamic update.
