Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-4303 medium priority: Ubuntu including 2 source packages (iperf, iperf3), 34 status rows across 17 suites (artful, bionic, cosmic, disco, eoan, focal, groovy, hirsute, impish, jammy, precise, trusty, upstream, wily, xenial, yakkety, zesty): not-affected 25, ignored 4, DNE 2, released 2, needs-triage 1.
The parse_string function in cjson.c in the cJSON library mishandles UTF8/16 strings, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a non-hex character in a JSON string, which triggers a heap-based buffer overflow.
