Summary: An update for bind is now available for Red Hat Enterprise Linux 8.0 Update Services for SAP Solutions. 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 E4S (v. 8.0) - aarch64, noarch, ppc64le, s390x, x86_64 Red Hat Enterprise Linux BaseOS E4S (v. 8.0) - 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: 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 6.
