Title: PHP Toolkit: Data disclosure and Denial of Service
Date: April 17, 2008
Bugs: #209535
ID: 200804-19
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
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"
