SQL injection vulnerability in prefs.php in phpBB 1.4.0 and 1.4.1 allows remote authenticated users to execute arbitrary SQL commands and gain administrative access via the viewemail parameter.

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.
