Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2018-15664 medium priority: Ubuntu including 1 source packages (docker.io), 6 status rows across 6 suites (bionic, cosmic, disco, trusty, upstream, xenial): released 5, DNE 1.
In Docker through 18.06.1-ce-rc2, the API endpoints behind the 'docker cp' command are vulnerable to a symlink-exchange attack with Directory Traversal, giving attackers arbitrary read-write access to the host filesystem with root privileges, because daemon/archive.go does not do archive operations on a frozen filesystem (or from within a chroot).
