Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-4436 medium priority: Ubuntu including 1 source packages (fwknop), 19 status rows across 19 suites (artful, bionic, cosmic, hardy, lucid, natty, oneiric, precise, quantal, raring, saucy, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): ignored 13, not-affected 3, DNE 2, released 1.
Buffer overflow in the run_last_args function in client/fwknop.c in fwknop before 2.0.3, when processing --last, might allow local users to cause a denial of service (client crash) and possibly execute arbitrary code via many .fwknop.run arguments.
