Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-2320 medium priority: Ubuntu including 1 source packages (connman), 16 status rows across 16 suites (hardy, lucid, natty, oneiric, precise, quantal, raring, saucy, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): ignored 11, DNE 2, not-affected 2, released 1.
ConnMan before 0.85 does not ensure that netlink messages originate from the kernel, which allows remote attackers to bypass intended access restrictions and cause a denial of service via a crafted netlink message.
