Description:
------------
Imagick does not respect SAFE_MODE restrictions. It can open files owned by other users, and does not apply the open_base_dir restriction.


Reproduce code:
---------------
<?php
$image='/root/test.jpg';

$handle=imagick_readimage($image);

if(imagick_iserror($handle))
    echo 'cant\'t read : ',$image,' <br>',
        imagick_failedreason($handle),imagick_faileddescription($handle);
else echo 'OK !';
?>

Expected result:
----------------
Image should not be accessed.

Actual result:
--------------
Image is correctly read.
