Synopsis

========

 

PHP Toolkit does not quote parameters, allowing for PHP source code

disclosure on Apache, and a Denial of Service.

 

Background

==========

 

PHP Toolkit is a utility to manage parallel installations of PHP within

Gentoo. It is executed by the PHP ebuilds at setup.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 app-admin/php-toolkit < 1.0.1 >= 1.0.1

 

Description

===========

 

Toni Arnold, David Sveningsson, Michal Bartoszkiewicz, and Joseph

reported that php-select does not quote parameters passed to the "tr"

command, which could convert the "-D PHP5" argument in the

"APACHE2_OPTS" setting in the file /etc/conf.d/apache2 to lower case.

 

Impact

======

 

An attacker could entice a system administrator to run "emerge php" or

call "php-select -t apache2 php5" directly in a directory containing a

lower case single-character named file, which would prevent Apache from

loading mod_php and thereby disclose PHP source code and cause a Denial

of Service.

 

Workaround

==========

 

Do not run "emerge" or "php-select" from a working directory which

contains a lower case single-character named file.

 

Resolution

==========

 

All PHP Toolkit users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=app-admin/php-toolkit-1.0.1"
