Bug #29333 output_buffering + trans_sess_id can corrupt session
Submitted: 2004-07-22 17:26 UTC Modified: 2004-07-23 06:14 UTC
From: alan at akbkhome dot com Assigned:
Status: Closed Package: Output Control
PHP Version: 4.3.8 OS: linux debian & redhat
Private report: No CVE-ID:
 [2004-07-22 17:26 UTC] alan at akbkhome dot com
Description:
------------
if output_buffering is set to 4096 and trans_sess_id is used, the output may be broken:

In the reproduce example, the trans_sess_id writes
<a href="/translators/index.php/calendar/view" ?phpsessid="fa562d5bb14df890e6db68627ea76442">



Reproduce code:
---------------
http://www.akbkhome.com/svn/test_trans/.htaccess
http://www.akbkhome.com/svn/test_trans/test.php
http://www.akbkhome.com/svn/test_trans/home.html.en.php


htaccess includes:

php_value session.use_cookies 0
php_value session.use_trans_sid 1 
php_value output_buffering 4098

test.php just sets up enough variables to render the HTML

home.html.en.php is just a HTML which happens to have the url link in the right place to reproduce the bug.



Expected result:
----------------
on the "View your personal calendar": 

<a href="/translators/index.php/calendar/view?phpsessid=fa562d5bb14df890e6db68627ea76442">



Actual result:
--------------
on the "View your personal calendar": 

<a href="/translators/index.php/calendar/view" ?phpsessid="fa562d5bb14df890e6db68627ea76442">
