The remote host is missing an update as announced via advisory SSA:2007-127-01.
New php packages are available for Slackware 10.2, 11.0, and -current to improve the stability and security of PHP. Quite a few bugs were fixed -- please see http://www.php.net for a detailed list. All sites that use PHP are encouraged to upgrade. Please note that we haven't tested all PHP applications for backwards compatibility with this new upgrade, so you should have the old package on hand just in case. Both PHP 4.4.7 and PHP 5.2.2 updates have been provided.
