If a readfile() function is passed 2nd parameter it can be used to read ANY file on the system regardless of safe_mode.

ex.

<?php
readfile('/etc/passwd', 1);
?>

Fixed in CVS (for all functions with a safemode_include_dir switch).  Note that this was only a problem if the safemode_include_dir was not defined in the php.ini file.
