Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-4868 low priority: Ubuntu including 1 source packages (isc-dhcp), 7 status rows across 7 suites (hardy, lucid, maverick, natty, oneiric, precise, upstream): DNE 3, not-affected 3, needs-triage 1.
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.
