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

An update for bind9.16 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 CRB (v. 8) - aarch64, noarch, 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.

Security Fix(es):

* bind: processing large delegations may severely degrade resolver
performance (CVE-2022-2795)

* bind: flooding with UPDATE requests may lead to DoS (CVE-2022-3094)

* bind: sending specific queries to the resolver may cause a DoS
(CVE-2022-3736)

* bind: sending specific queries to the resolver may cause a DoS
(CVE-2022-3924)

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.
