  - CVE-2015-3627: Docker opens the file-descriptor passed to the pid-1 process before performing
  the chroot, which allows local users to gain privileges via a symlink attack in an image.

  - CVE-2015-3629: Docker allows local users to escape containerization ('mount namespace breakout')
  and write  to arbitrary file on the host system via a symlink attack in an image when respawning
  a container.

  - CVE-2015-3630: Docker uses weak permissions for /proc/asound, /proc/timer_stats,
  /proc/latency_stats, and /proc/fs, which allows local users to modify the host, obtain sensitive
  information, and perform protocol downgrade attacks via a crafted image.

  - CVE-2015-3631: Docker allows local users to set arbitrary Linux Security Modules (LSM) and
  docker_t policies via an image that allows volumes to override files in /proc.");
