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" References ========== [ 1 ] CVE-2008-1734 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1734 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200804-19.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
