A missing check on incoming client requests can be exploited to cause a
situation where the Kea server’s lease storage contains leases which are
rejected as invalid when the server tries to load leases from storage on
restart. If the number of such leases exceeds a hard-coded limit in the Kea
code, a server trying to restart will conclude that there is a problem with
its lease store and give up. Versions affected: 1.4.0 to 1.5.0,
1.6.0-beta1, and 1.6.0-beta2
