Checks for image file format denial of service vulnerabilities in PHP Detailed Explanation for this Vulnerability Assessment Summary : The remote web server is prone to denial of service attacks. Description : 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, a possible hacker can trigger an infinite loop when 'getimagesize' is called, perhaps even remotely in the case image uploads are permited.
