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: 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.

Bug Fix(es):

  • BIND stops DNSKEY lookup in get_dst_key() when a key with unsupported algorithm is found first [RHEL7] (BZ#1884530)
