Bug #37720 merge_php_config scrambles values when using DirectoryMatch / VirtualHost
Submitted: 2006-06-06 22:05 UTC Modified: 2006-06-09 15:16 UTC
From: pumuckel at metropolis dot de Assigned:
Status: Closed Package: Apache2 related
PHP Version: 5.1.4 OS: Linux
Private report: No CVE-ID:
 [2006-06-06 22:05 UTC] pumuckel at metropolis dot de
Description:
------------
When using DirectoryMatch in httpd.conf / .htaccess and virtualHost entries, then php_values inside those directives get scrambled. The reason seems likely to be that in merge_php_config the new_conf parameter gets modified even this is strictly forbidden by apache2 api!

Solution: Make a copy of new_conf (with proper hash initialization) and return a pointer to the new copy.


Reproduce code:
---------------
I can provide a testcase configuration on request.

Expected result:
----------------
The configuration parameters should be as configured.

Actual result:
--------------
Configuration is mixed occasionally.

Please upload it somewhere and put the link here.

It'd be good to have a couple of examples.
