Description:
This update for bind fixes the following issues:
– An attacker with the ability to send and receive messages to an
authoritative DNS server was able to circumvent TSIG authentication of
AXFR requests. A server that relied solely on TSIG keys for protection
could be manipulated into (1) providing an AXFR of a zone to an
unauthorized recipient and (2) accepting bogus Notify packets.

– An attacker who with the ability to send and receive messages to an
authoritative DNS server and who had knowledge of a valid TSIG key name
for the zone and service being targeted was able to manipulate BIND into
accepting an unauthorized dynamic update. [bsc#1046555, CVE-2017-3143]
