GLSA-200402-01 : PHP setting leaks from .htaccess files on virtual hosts

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200402-01
(PHP setting leaks from .htaccess files on virtual hosts)

If the server configuration 'php.ini' file has
'register_globals = on' and a request is made to one virtual host
(which has 'php_admin_flag register_globals off') and the next
request is sent to the another virtual host (which does not have the
setting) through the same apache child, the setting will persist.

Impact :

Depending on the server and site, an attacker may be able to exploit
global variables to gain access to reserved areas, such as MySQL passwords,
or this vulnerability may simply cause a lack of functionality. As a
result, users are urged to upgrade their PHP installations.
Gentoo ships PHP with 'register_globals' set to 'off'
by default.
This issue affects both servers running Apache 1.x and servers running
Apache 2.x.

Workaround :

No immediate workaround is available
a software upgrade is required.
