Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-2502 medium priority: Ubuntu including 1 source packages (systemtap), 9 status rows across 9 suites (hardy, lucid, maverick, natty, oneiric, precise, quantal, raring, upstream): ignored 4, not-affected 4, released 1.
runtime/staprun/staprun_funcs.c in the systemtap runtime tool (staprun) in SystemTap before 1.6 does not properly validate modules when a module path is specified by a user for user-space probing, which allows local users in the stapusr group to gain privileges via a crafted module in the search path in the -u argument.
