Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-1570 medium priority: Ubuntu including 1 source packages (maradns), 20 status rows across 20 suites (artful, bionic, cosmic, hardy, lucid, maverick, natty, oneiric, precise, quantal, raring, saucy, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): ignored 15, not-affected 3, DNE 1, released 1.
The resolver in MaraDNS before 1.3.0.7.15 and 1.4.x before 1.4.12 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "ghost domain names" attack.
