PHP Toolkit: Data disclosure and Denial of Service1. Gentoo Linux Security Advisory
Related bugreports: #209535 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. 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:
