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 9 resolvers configured to answer from cache with zero stale-answer-timeout may terminate unexpectedly (CVE-2022-3080)
  • bind: memory leak in ECDSA DNSSEC verification code (CVE-2022-38177)
  • bind: memory leaks in EdDSA DNSSEC verification code (CVE-2022-38178)
