Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-7484 low priority: Ubuntu including 5 source packages (postgresql-10, postgresql-9.1, postgresql-9.3, postgresql-9.5, postgresql-9.6), 44 status rows across 9 suites (artful, bionic, cosmic, disco, trusty, upstream, xenial, yakkety, zesty): DNE 32, released 5, not-affected 3, needed 2, ignored 1, needs-triage 1.
It was found that some selectivity estimation functions in PostgreSQL before 9.2.21, 9.3.x before 9.3.17, 9.4.x before 9.4.12, 9.5.x before 9.5.7, and 9.6.x before 9.6.3 did not check user privileges before providing information from pg_statistic, possibly leaking information. An unprivileged attacker could use this flaw to steal some information from tables they are otherwise not allowed to access.
