Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-4405 high priority: Ubuntu including 1 source packages (system-config-printer), 6 status rows across 6 suites (hardy, lucid, maverick, natty, oneiric, upstream): not-affected 2, released 2, ignored 1, needs-triage 1.
The cupshelpers scripts in system-config-printer in Ubuntu 11.04 and 11.10, as used by the automatic printer driver download service, uses an "insecure connection" for queries to the OpenPrinting database, which allows remote attackers to execute arbitrary code via a man-in-the-middle (MITM) attack that modifies packages or repositories.
