"Several vulnerabilities were discovered in BIND, a DNS server
implementation. The Common Vulnerabilities and Exposures project
identifies the following problems :

  - 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 ."
