Note that this update addresses the recent FileVault password
vulnerability, in which user passwords are stored in plaintext to a
system-wide debug log if the legacy version of FileVault is used to
encrypt user directories after a system upgrade to Lion. Since the
patch only limits further exposure, though, we recommend that all
users on the system change their passwords if user folders were
encrypted using the legacy version of FileVault prior to and after an
upgrade to OS X 10.7."
