prefs.php in phpBB 1.4.0 and earlier allows remote authenticated users to execute arbitrary PHP code via an invalid language value, which prevents the variables (1) $l_statsblock in prefs.php or (2) $l_privnotify in auth.php from being properly initialized, which can be modified by the user and later used in an eval statement.
