Public bug reported:

Binary package hint: ecryptfs-utils

ecryptfs-setup-private potentially exposes passwords in the process
table.

There are two calls in ecryptfs-setup-private to helper utilities:
 * ecryptfs-wrap-passphrase
 * ecryptfs-add-passphrase
that use passwords on the command line.

There is a small yet real possibility that these passwords could be
exposed on the process table momentarily.

To fix this problem, we need to:
 a) patch both ecryptfs-wrap-passphrase and ecryptfs-add-passphrase to take passphrases on stdin
 b) modify the callers to use a dash/bash builtin function (such as echo or printf) to send this passphrases to those utilities on standard in

Thanks to Jamie Strandboge for the bug report.
