CVE-2018-15664 (opens in a new tab)How to fix?
Upgrade Ubuntu:16.04 docker.io to version 18.09.7-0ubuntu1~16.04.4 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream docker.io package and not the docker.io package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
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).
