Bug Type: *Configuration Issues
Operating System: FreeBSD 4.10
PHP Version: 4.4.4
New Comment:
Also I have made a test, copying new ext/session (php 4.4.4) to old
distributive (4.3.11), but i haven't got this Warning.
It seems to be a bug in Apache per VirtualHost php runtime settings at
4.4 branch.

I have checked the diffs of session.c implementations between 4.3.11
and php4-latest-snapshot, here is the same that brought my attention.
As i understand correctly, there is implementation of checking
boundaries such as open_basedir at runtime if it was got from Apache
VirtualHost section.
So, the problem was from the beginning of 4 branch??? Is there a
security leak, cause sessions sometimes got their paths from other
VirtualHost???

Description:
------------
I got a problem with open_basedir between Apache's (2.0.55) virtual
hosts.
This error appeared in 4.4.x branch!
PHP 4.3.11 does NOT have this error.
----------------------------------------
Warning: Unknown(): open_basedir restriction in effect.
File(/pub/home/xxxxxxx/tmp) is not within the allowed path(s):
(/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/php/lib/php:/usr/local/mysql/bin:/pub/home/yyyyyyyy)
in Unknown on line 0
----------------------------------------
This is very serious bug and it stops us from using PHP 4.4.x
Reproduce code:
---------------
<VirtualHost aaa.aaa.aaa.aaa:80>
..............
php_admin_value doc_root '/pub/home/xxxxxxx'
php_admin_value upload_tmp_dir '/pub/home/xxxxxxx/tmp'
php_admin_value session.save_path '/pub/home/xxxxxxx/tmp'
php_admin_value open_basedir
'/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/php/lib/php:/usr/local/
mysql/bin:/pub/home/xxxxxxx'
..............
</VirtualHost>
<VirtualHost aaa.aaa.aaa.aaa:80>
..............
php_admin_value doc_root '/pub/home/yyyyyyyy'
php_admin_value upload_tmp_dir '/pub/home/yyyyyyyy/tmp'
php_admin_value session.save_path '/pub/home/yyyyyyyy/tmp'
php_admin_value open_basedir
'/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/php/lib/php:/usr/local/
mysql/bin:/pub/home/yyyyyyyy'
..............
</VirtualHost>
