CVE-2018-15664 Information

Description

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).
