Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-1097 medium priority: Ubuntu including 29 source packages (linux, linux-armadaxp, …), 353 status rows across 17 suites (hardy, lucid, maverick, natty, oneiric, precise, quantal, raring, saucy, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): DNE 252, not-affected 51, released 39, ignored 11.
The regset (aka register set) feature in the Linux kernel before 3.2.10 does not properly handle the absence of .get and .set methods, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a (1) PTRACE_GETREGSET or (2) PTRACE_SETREGSET ptrace call.
