Docker before 1.3.2 allows remote attackers to write to arbitrary files and execute arbitrary code via a (1) symlink or (2) hard link attack in an image archive in a (a) pull or (b) load operation.
Docker 1.3.0 through 1.3.1 allows remote attackers to modify the default run profile of image containers and possibly bypass the container by applying unspecified security options to an image.
