Title: PHP Toolkit: Data disclosure and Denial of Service (GLSA 200804-19)
Date: April 17, 2008
PHP Toolkit does not quote parameters, allowing for PHP source code disclosure on Apache, and a Denial of Service.
PHP Toolkit is a utility to manage parallel installations of PHP within Gentoo. It is executed by the PHP ebuilds at setup.
Vulnerable: < 1.0.1
Unaffected: >= 1.0.1
Architectures: All supported architectures
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.
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.
Do not run "emerge" or "php-select" from a working directory which contains a lower case single-character named file.
All PHP Toolkit users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/php-toolkit-1.0.1"
