PHP v4.4.4, v5.1.6, y otras versiones, cuando están ejecutando Apache, permite a usuarios locales modificar el comportamiento de otros sitios hospedados en el mismo servidor web mediante la modificación de la característica mbstring.func_overload dentro de .htaccess, lo que produce que esta característica sea aplicada a otros sistemas virtuales alojados en el mismo servidor.
