Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

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.
