"According to its banner, the version of PHP installed on the remote
host is vulnerable to a denial of service attack due to its failure to
properly validate file data in the routines 'php_handle_iff' and
'php_handle_jpeg', which are called by the PHP function
'getimagesize'.  Using a specially crafted image file, an attacker can
trigger an infinite loop when 'getimagesize' is called, perhaps even
remotely in the cases where image uploads are allowed.");
