The logging functionality in dhcpd in ISC DHCP before 4.2.3-P2, when using
Dynamic DNS (DDNS) and issuing IPv6 addresses, does not properly handle the
DHCPv6 lease structure, which allows remote attackers to cause a denial of
service (NULL pointer dereference and daemon crash) via crafted packets
related to a lease-status update.

Notes

Author Note
mdeslaur vulnerable code was added in 4.2.2, and fixed in 4.2.3-P2
