The remote host is missing updates announced in advisory GLSA 200402-01.

All users are recommended to upgrade their PHP installation to 4.3.4-r4: # emerge sync # emerge -pv '>=dev-php/mod_php-4.3.4-r4' # emerge '>=dev-php/mod_php-4.3.4-r4' http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200402-01 http://bugs.gentoo.org/show_bug.cgi?id=39952 http://bugs.php.net/bug.php?id=25753

If the server configuration ' php.ini ' file has ' register_globals = on ' and a request is made to one virtual host (which has ' php_admin_flag register_globals off ' ) and the next request is sent to the another virtual host (which does not have the setting) global variables may leak and may be used to exploit the site.
