-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: bind security update Advisory ID: RHSA-2021:2028-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:2028 Issue date: 2021-05-19 CVE Names: CVE-2021-25215 ==================================================================== 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: Red Hat Enterprise Linux AppStream EUS (v. 8.1) - aarch64, noarch, ppc64le, s390x, x86_64 Red Hat Enterprise Linux BaseOS EUS (v. 8.1) - 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. Security Fix(es): * bind: An assertion check can fail while answering queries for DNAME records that require the DNAME to be processed to resolve itself (CVE-2021-25215) 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/): 1953857 - CVE-2021-25215 bind: An assertion check can fail while answering queries for DNAME records that require the DNAME to be processed to resolve itself 6.
