Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-1930 low priority: Ubuntu including 1 source packages (klibc), 13 status rows across 13 suites (hardy, lucid, maverick, natty, oneiric, precise, quantal, raring, saucy, trusty, upstream, utopic, vivid): not-affected 8, ignored 4, released 1.
In klibc 1.5.20 and 1.5.21, the DHCP options written by ipconfig to /tmp/net-$DEVICE.conf are not properly escaped. This may allow a remote attacker to send a specially crafted DHCP reply which could execute arbitrary code with the privileges of any process which sources DHCP options.
