3. Description:

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.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

After installing the update, the BIND daemon (named) will be restarted
automatically.
