Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-5384 medium priority: Ubuntu including 1 source packages (fontconfig), 6 status rows across 6 suites (precise, trusty, upstream, xenial, yakkety, zesty): released 6.
fontconfig before 2.12.1 does not validate offsets, which allows local users to trigger arbitrary free calls and consequently conduct double free attacks and execute arbitrary code via a crafted cache file.
