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 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)

Note: This issue affected only the BIND versions as shipped with Red Hat
Enterprise Linux 6. This issue did not affect any upstream versions of
BIND.

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.
