"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 ."

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The Berkeley Internet Name Domain (BIND) is an implementation of the
Domain Name System (DNS) protocols. BIND includes a DNS server
(named); a resolver library (routines for applications to use when
interfacing with DNS); and tools for verifying that the DNS server is
operating correctly.

Security Fix(es) :

* A denial of service flaw was found in the way BIND handled a query
response containing CNAME or DNAME resource records in an unusual
order. A remote attacker could use this flaw to make named exit
unexpectedly with an assertion failure via a specially crafted DNS
response. (CVE-2017-3137)

* A denial of service flaw was found in the way BIND handled DNSSEC
validation. A remote attacker could use this flaw to make named exit
unexpectedly with an assertion failure via a specially crafted DNS
response. (CVE-2017-3139)

Red Hat would like to thank ISC for reporting CVE-2017-3137.

Bug Fix(es) :

* ICANN is planning to perform a Root Zone DNSSEC Key Signing Key
(KSK) rollover during October 2017. Maintaining an up-to-date KSK, by
adding the new root zone KSK, is essential for ensuring that
validating DNS resolvers continue to function following the rollover.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The Berkeley Internet Name Domain (BIND) is an implementation of the
Domain Name System (DNS) protocols. BIND includes a DNS server
(named); a resolver library (routines for applications to use when
interfacing with DNS); and tools for verifying that the DNS server is
operating correctly.

Security Fix(es) :

* A denial of service flaw was found in the way BIND handled a query
response containing CNAME or DNAME resource records in an unusual
order. A remote attacker could use this flaw to make named exit
unexpectedly with an assertion failure via a specially crafted DNS
response. (CVE-2017-3137)

* A denial of service flaw was found in the way BIND handled query
requests when using DNS64 with 'break-dnssec yes' option. A remote
attacker could use this flaw to make named exit unexpectedly with an
assertion failure via a specially crafted DNS request. (CVE-2017-3136)

Red Hat would like to thank ISC for reporting these issues. Upstream
acknowledges Oleg Gorokhov (Yandex) as the original reporter of
CVE-2017-3136.

preceding description block directly from the corresponding Red Hat

"From Red Hat Security Advisory 2017:1105 :

An update for bind is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The Berkeley Internet Name Domain (BIND) is an implementation of the
Domain Name System (DNS) protocols. BIND includes a DNS server
(named); a resolver library (routines for applications to use when
interfacing with DNS); and tools for verifying that the DNS server is
operating correctly.

Security Fix(es) :

* A denial of service flaw was found in the way BIND handled a query
response containing CNAME or DNAME resource records in an unusual
order. A remote attacker could use this flaw to make named exit
unexpectedly with an assertion failure via a specially crafted DNS
response. (CVE-2017-3137)

* A denial of service flaw was found in the way BIND handled query
requests when using DNS64 with 'break-dnssec yes' option. A remote
attacker could use this flaw to make named exit unexpectedly with an
assertion failure via a specially crafted DNS request. (CVE-2017-3136)

Red Hat would like to thank ISC for reporting these issues. Upstream
acknowledges Oleg Gorokhov (Yandex) as the original reporter of
CVE-2017-3136."
