  script_tag(name:"insight", value:"runc through 1.0-rc6, as used in Docker, allows attackers to
  overwrite the host runc binary (and consequently obtain host root access) by leveraging the
  ability to execute a command as root within one of these types of containers: (1) a new container
  with an attacker-controlled image, or (2) an existing container, to which the attacker previously
  had write access, that can be attached with docker exec. This occurs because of file-descriptor
  mishandling, related to /proc/self/exe.");
