====================================================================
1. Summary:

An update for bind is now available for Red Hat Enterprise Linux 8.1
Extended Update Support.

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.

2. Relevant releases/architectures:

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: BIND does not sufficiently limit the number of fetches performed
when processing referrals (CVE-2020-8616)

* bind: A logic error in code which checks TSIG validity can be used to
trigger an assertion failure in tsig.c (CVE-2020-8617)

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

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/):

1836118 - CVE-2020-8616 bind: BIND does not sufficiently limit the number of fetches performed when processing referrals
1836124 - CVE-2020-8617 bind: A logic error in code which checks TSIG validity can be used to trigger an assertion failure in tsig.c
