Question: When a parent Set - UID process ( effective user ID is root, and the real user ID is bob ) creates a child process

When a parent Set-UID process (effective user ID is root, and the real user ID is bob)
creates a child process using fork(), the standard input, output, and error devices of
the parent will be inherited by the child. If the child process drops its root privilege,
it still retains the access right to these devices. This seems to be a capability leaking,
similar to the capability-leaking case covered in this chapter. Can this pose any danger?
