Issue date: 2020-11-03
CVE Names: CVE-2020-8619 CVE-2020-8622 CVE-2020-8623
CVE-2020-8624
=====================================================================

1. Summary:

An update for bind is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact
of Moderate. 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:

Red Hat Enterprise Linux AppStream (v. 8) – aarch64, noarch, ppc64le, s390x, x86_64
Red Hat Enterprise Linux BaseOS (v. 8) – aarch64, ppc64le, s390x, x86_64

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.

The following packages have been upgraded to a later upstream version: bind
(9.11.20). (BZ#1818785)

Security Fix(es):

* bind: asterisk character in an empty non-terminal can cause an assertion
failure in rbtdb.c (CVE-2020-8619)

* bind: truncated TSIG response can lead to an assertion failure
(CVE-2020-8622)

* bind: remotely triggerable assertion failure in pk11.c (CVE-2020-8623)

* bind: incorrect enforcement of update-policy rules of type “subdomain”
(CVE-2020-8624)

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.

Additional Changes:

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 8.3 Release Notes linked from 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/):

1693395 – Remove revoked KSK from trusted keys
1749505 – internal test suite failures
1814158 – bind internal testsuite, random failure in autosign
