ISC reports:
Due to improper handling of a DHCPv6 lease structure, ISC DHCP
servers that are serving IPv6 address pools AND using Dynamic
DNS can encounter a segmentation fault error while updating lease
status under certain conditions.
The potential exists for this condition to be intentionally
triggered, resulting in effective denial of service to
clients expecting service from the affected server.
