IMPORTANT INFORMATION
There was a serious vulnerability in certain CGI-based PHP setups that has gone unnoticed for at least 8 years.
For PHP this means that a request containing ?-s may dump the PHP source code for the page.
Make sure to update to current versions and/or use an .htaccess patch, both available here:
PHP 5.3.12 and PHP 5.4.2 Released:
