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):

* bind: processing of certain records when "deny-answer-aliases" is in
use
may trigger an assert leading to a denial of service (CVE-2018-5740)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Red Hat would like to thank ISC for reporting this issue. Upstream
acknowledges Tony Finch (University of Cambridge) as the original reporter.

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.

5. Bugs fixed (https://bugzilla.redhat.com/):
