Title

Processing large delegations may severely degrade resolver performance

Summary

Severity

5.3 (Medium)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L

CWE

In BIND 9.0.0 -> 9.16.32, 9.18.0 -> 9.18.6, versions 9.9.3-S1 -> 9.11.37-S1, 9.16.8-S1 -> 9.16.32-S1 of the BIND Supported Preview Edition, and versions 9.19.0 -> 9.19.4 of the BIND 9.19 development branch, a flaw in resolver code can cause named to spend excessive amounts of time on processing large delegations.
