"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 :

  - providing an AXFR of a zone to an unauthorized recipient

  - 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.

For Debian 7 'Wheezy', these problems have been fixed in version
1:9.8.4.dfsg.P1-6+nmu2+deb7u18.

We recommend that you upgrade your bind9 packages.
