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: processing large delegations may severely degrade resolver performance (CVE-2022-2795)

  • bind: flooding with UPDATE requests may lead to DoS (CVE-2022-3094)

  • bind: sending specific queries to the resolver may cause a DoS (CVE-2022-3736)

  • bind: sending specific queries to the resolver may cause a DoS (CVE-2022-3924)
