Summary

Docker Machine through 0.16.2 allows an attacker, who has control of a worker node, to provide crafted version data, which might potentially trick an administrator into performing an unsafe action (via escape sequence injection), or might have a data size that causes a denial of service to a bastion node. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
