Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-2563 medium priority: Ubuntu including 1 source packages (putty), 11 status rows across 11 suites (artful, bionic, cosmic, disco, precise, trusty, upstream, wily, xenial, yakkety, zesty): not-affected 7, ignored 2, DNE 1, released 1.
Stack-based buffer overflow in the SCP command-line utility in PuTTY before 0.67 and KiTTY 0.66.6.3 and earlier allows remote servers to cause a denial of service (stack memory corruption) or execute arbitrary code via a crafted SCP-SINK file-size response to an SCP download request.
