  <title>PHP Toolkit: Data disclosure and Denial of service</title>
  <synopsis>
    PHP Toolkit does not quote parameters, allowing for PHP source code
    disclosure on Apache, and a Denial of Service.

  <background>
    <p>
    PHP Toolkit is a utility to manage parallel installations of PHP within
    Gentoo. It is executed by the PHP ebuilds at setup.

  <description>
    <p>
    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.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could entice a system administrator to run "<i>emerge
    php</i>" or call "<i>php-select -t apache2 php5</i>" 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.
    </p>
  </impact>
  <workaround>
    <p>
    Do not run "emerge" or "php-select" from a working directory which
    contains a lower case single-character named file.
    </p>
  </workaround>
  <resolution>
    <p>
    All PHP Toolkit users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-admin/php-toolkit-1.0.1"</code>
  </resolution>
