"CVE-2017-3136

Oleg Gorokhov of Yandex discovered that BIND does not properly handle
certain queries when using DNS64 with the 'break-dnssec yes;' option,
allowing a remote attacker to cause a denial of service.

CVE-2017-3137

It was discovered that BIND makes incorrect assumptions about the
ordering of records in the answer section of a response containing
CNAME or DNAME resource records, leading to situations where BIND
exits with an assertion failure. An attacker can take advantage of
this condition to cause a denial of service.

CVE-2017-3138

Mike Lalumiere of Dyn, Inc. discovered that BIND can exit with a
REQUIRE assertion failure if it receives a null command string on its
control channel. Note that the fix applied in Debian is only applied
as a hardening measure. Details about the issue can be found at
https://kb.isc.org/article/AA-01471 .

For Debian 7 'Wheezy', these problems have been fixed in version
1:9.8.4.dfsg.P1-6+nmu2+deb7u16.

We recommend that you upgrade your bind9 packages.
