-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: bind9.16 security and bug fix update Advisory ID: RHSA-2023:2792-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2023:2792 Issue date: 2023-05-16 CVE Names: CVE-2022-2795 CVE-2022-3094 CVE-2022-3736 CVE-2022-3924 ==================================================================== 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. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.8 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 5. Bugs fixed (https://bugzilla.redhat.com/): 2115322 - bind9.16-dnssec-utils should be in AppStream repository 2128584 - CVE-2022-2795 bind: processing large delegations may severely degrade resolver performance 2164032 - CVE-2022-3094 bind: flooding with UPDATE requests may lead to DoS 2164038 - CVE-2022-3736 bind: sending specific queries to the resolver may cause a DoS 2164039 - CVE-2022-3924 bind: sending specific queries to the resolver may cause a DoS 6.
