Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-2922 high priority: Ubuntu including 1 source packages (ktsuss), 10 status rows across 10 suites (hardy, lucid, maverick, natty, oneiric, precise, quantal, raring, saucy, upstream): DNE 6, ignored 3, needs-triage 1.
ktsuss versions 1.4 and prior spawns the GTK interface to run as root. This can allow a local attacker to escalate privileges to root and use the "GTK_MODULES" environment variable to possibly execute arbitrary code.
