Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-3954 medium priority: Ubuntu including 2 source packages (dhcp3, isc-dhcp), 12 status rows across 6 suites (hardy, lucid, natty, oneiric, precise, upstream): DNE 5, released 3, needs-triage 2, not-affected 2.
Multiple memory leaks in ISC DHCP 4.1.x and 4.2.x before 4.2.4-P1 and 4.1-ESV before 4.1-ESV-R6 allow remote attackers to cause a denial of service (memory consumption) by sending many requests.
