* regression: docker cp: Rel: can't make /..../a relative to a (BZ#1723491)

* Regression: docker cp: can no longer pull image files (BZ#1727488)

CVE-2018-15664
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).
