Bug description:tempnam(): wrong fallback to /tmp
Description:
------------
tempnam() should NOT fall back to /tmp if the $dir-param is explicit set to
a real-path inside the open_basedir and because of wrong permissions $dir
is not writeable
Test script:
---------------
<?php
$temp_folder = dirname(__FILE__) . '/temp/';
mkdir($temp_folder);
chmod($temp_folder, 0555);
$tmp_name = str_replace("\\", '/', tempnam($temp_folder, 'rhcsv'));
$fp = fopen($tmp_name, 'wb+');
if($fp)
{
flock($fp, LOCK_EX);
fwrite($fp, 'test');
flock($fp, LOCK_UN);
fclose($fp);
}
?>
Expected result:
----------------
error message that $dir is not writeable
Actual result:
--------------
temporary file is created in /tmp which violates open_basedir and fopen()
is failing with open_basedir restriction messages
