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 1817870 - /usr/bin/nsupdate -g segfault when connect to AD 1847244 - CVE-2020-8619 bind: asterisk character in an empty non-terminal can cause an assertion failure in rbtdb.c 1848169 - named-checkconf fails to validate configuration file with CIDRs with host bits set 1859454 - named-pkcs11.service: (named-pkcs11) of user 25 dumped core. 1869473 - CVE-2020-8622 bind: truncated TSIG response can lead to an assertion failure 1869477 - CVE-2020-8623 bind: remotely triggerable assertion failure in pk11.c 1869480 - CVE-2020-8624 bind: incorrect enforcement of update-policy rules of type "subdomain" 6.
