The remote Debian host is missing a security-related update.
Several vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development : - CVE-2014-0185 The default PHP FPM socket permission has been changed from 0666 to 0660 to mitigate a security vulnerability ( CVE-2014-0185 ) in PHP FPM that allowed any local user to run a PHP code under the active user of FPM process via crafted FastCGI client. The default Debian setup now correctly sets the listen.owner and listen.group to www-data:www-data in default php-fpm.conf. If you have more FPM instances or a webserver not running under www-data user you need to adjust the configuration of FPM pools in /etc/php5/fpm/pool.d/ so the accessing process has rights to access the socket. - CVE-2014-0237 / CVE-2014-0238 Denial of service in the CDF parser of the fileinfo module. - CVE-2014-2270 Denial of service in the fileinfo module.
Upgrade the php5 packages. For the stable distribution (wheezy), these problems have been fixed in version 5.4.4-14+deb7u10.
