GLSA 200804-19: PHP Toolkit: Data disclosure and Denial of Service

http://security.gentoo.org/

Severity:	normal
Title:	PHP Toolkit: Data disclosure and Denial of Service
Date:	04/17/2008
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	Architecture(s)
app-admin/php-toolkit	< 1.0.1	>= 1.0.1	All supported architectures

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"
