  <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. [bsc#1046554, CVE-2017-3142]

- 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]
