Hi,
in my understanding "dd" is only a data shuffling program without magic features like suid root, etc.
Every program should be able to open(2) a character special device file IF the EUID/EGID properties of the resulting process allows writing to the devices (disk partitions). Note that they are normaly owned by root.
