Summary
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)

Processing large delegations may severely degrade resolver performance
By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service.
