According to its banner, the version of PHP 5.6.x installed on the remote host is prior to 5.6.6. It is, therefore, affected by multiple vulnerabilities :
A heap-based buffer overflow flaw in the enchant_broker_request_dict function in ext/enchant/enchant.c could allow a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2014-9705)
A heap-based buffer overflow flaw in the GNU C Library (glibc) due to improperly validating user-supplied input in the glibc functions __nss_hostname_digits_dots(), gethostbyname(), and gethostbyname2(). This allows a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-0235)
A use-after-free flaw exists in the function php_date_timezone_initialize_from_hash() within the ‘ext/date/php_date.c’ script. An attacker can exploit this to access sensitive information or crash applications linked to PHP. (CVE-2015-0273)
A use-after-free vulnerability in the phar_rename_archive function in phar_object.c could allow a remote attacker to cause a denial of service.
(CVE-2015-2301)
An XML External Entity (XXE) flaw exists in the PHP-FPM component due to improper parsing of XML data. A remote attacker can exploit this, via specially crafted XML data, to disclose sensitive information or cause a denial of service. (CVE-2015-8866)
Note that Nessus has not attempted to exploit these issues but has instead relied only on the application’s self-reported version number.
