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)
