Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2011-2503 not yet assigned priority: Debian including 1 source packages (systemtap), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
The insert_module function in runtime/staprun/staprun_funcs.c in the systemtap runtime tool (staprun) in SystemTap before 1.6 does not properly validate a module when loading it, which allows local users to gain privileges via a race condition between the signature validation and the module initialization.
