PHP Multiple Image Processing Functions File Handling DoS

Medium Nessus Plugin ID 17687


The remote web server is prone to denial of service attacks.


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.


Upgrade to PHP 4.3.11 / 5.0.4 or later.
