Vendor Solution
Upgrade to the patched release most closely related to your current version of BIND. These can all be downloaded from http://www.isc.org/downloads. BIND 9 version 9.9.10-P2 BIND 9 version 9.10.5-P2 BIND 9 version 9.11.1-P2 BIND Supported Preview Edition is a special feature preview branch of BIND provided to eligible ISC support customers. BIND 9 version 9.9.10-S3 BIND 9 version 9.10.5-S3
Vendor Workaround
The effects of this vulnerability can be mitigated by using Access Control Lists (ACLs) that require both address range validation and use of TSIG authentication in conjunction. For information on how to configure this type of compound authentication control, please see: https://kb.isc.org/article/AA-00723/0/Using-Access-Control-Lists-ACLs-with-both-addresses-and-keys.html. (Note that this technique may not be effective against bogus NOTIFY packets if an attacker is able to reach the target DNS server whilst using a spoofed sending address).

EUVD-2017-12283 | 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.
