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).

En Docker hasta la versión 18.06.1-ce-rc2, los endpoints API debajo del comando 'docker cp' son vulnerables a un ataque de de tipo symlink-exchange con salto de directorio, dando a los atacantes acceso arbitrario de lectura-escritura al sistema de archivos del host con privilegios de root, porque daemon/archive.go no genera operaciones de archivo en un filesystem congelado (o desde dentro de una operación chroot).
