CVE-2019-6474 - log back

CVE-2019-6474 created at 25 Sep 2019 19:31:40
Severity	+ High
Remote	+ Remote
Type	+ Denial of service
Description	+ An issue has been found in the Kea DHCPv6 server before 1.6.0 or 1.5.0-P1, where 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.
