Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-2207 low priority: Ubuntu including 1 source packages (dirmngr), 10 status rows across 10 suites (hardy, lucid, maverick, natty, oneiric, precise, quantal, raring, saucy, upstream): not-affected 5, ignored 4, released 1.
dirmngr before 2.1.0 improperly handles certain system calls, which allows remote attackers to cause a denial of service (DOS) via a specially-crafted certificate.
