<blockquote cite="https://www.isc.org/software/dhcp/advisories/cve-2011-4868">
<p>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.</p>
<p>The potential exists for this condition to be intentionally
triggered, resulting in effective denial of service to
clients expecting service from the affected server.</p>
