Docker: Race condition in docker cp allows creation of arbitrary empty files on the host via symlink swap

Summary A race condition during docker cp mount setup allows a malicious container to create empty files or directories at arbitrary absolute paths on the host filesystem. This advisory covers the race during mountpoint creation. The related race during the subsequent mount syscall is tracked in...
