CVE-2011-4868 Information

Description

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.
