According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.25. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the object_common2()     function in var_unserializer.c that occurs when handling     objects during deserialization. An unauthenticated,     remote attacker can exploit this to execute arbitrary     code. (CVE-2016-7124)

  - An unspecified flaw exists in session.c that occurs     when handling session names. An unauthenticated, remote     attacker can exploit this to inject arbitrary data into     sessions. (CVE-2016-7125)

  - An integer truncation flaw exists in the select_colors()     function in gd_topal.c that is triggered when handling     the number of colors. An unauthenticated, remote     attacker can exploit to cause a heap-based buffer     overflow, resulting in the execution of arbitrary code.
    (CVE-2016-7126)

  - An indexing flaw exists in the imagegammacorrect()     function in gd.c that occurs when handling negative     gamma values. An unauthenticated, remote attacker can     exploit this to write a NULL to an arbitrary memory     location, resulting in a denial of service condition or     the execution of arbitrary code. (CVE-2016-7127)

  - A flaw exists in the exif_process_IFD_in_TIFF() function     in exif.c that occurs when handling TIFF image content.
    An unauthenticated, remote attacker can exploit this to     disclose memory contents. (CVE-2016-7128)

  - A flaw exists in the php_wddx_process_data() function in     wddx.c that occurs when deserializing invalid dateTime     values. An unauthenticated, remote attacker can exploit     this to cause a denial of service condition.
    (CVE-2016-7129)

  - A NULL pointer dereference flaw exists in the     php_wddx_pop_element() function in wddx.c that is     triggered during the handling of Base64 binary values.
    An unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2016-7130)

  - A NULL pointer dereference flaw exists in the     php_wddx_deserialize_ex() function in wddx.c that occurs     during the handling of invalid XML content. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2016-7131)

  - An unspecified NULL pointer dereference flaw exists in     the php_wddx_pop_element() function in wddx.c. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition. CVE-2016-7132)

  - An integer overflow condition exists in the     php_snmp_parse_oid() function in snmp.c. An     unauthenticated, remote attacker can exploit this to     cause a heap-based buffer overflow, resulting in the     execution of arbitrary code.

  - An overflow condition exists in the sql_regcase()     function in ereg.c due to improper handling of overly     long strings. An unauthenticated, remote attacker     can exploit this to corrupt memory, resulting in the     execution of arbitrary code.

  - An integer overflow condition exists in the     php_base64_encode() function in base64.c that occurs     when handling overly long strings. An unauthenticated,     remote attacker can exploit this to execute arbitrary     code.

  - An integer overflow condition exists in the     php_quot_print_encode() function in quot_print.c that     occurs when handling overly long strings. An     unauthenticated, remote attacker can exploit this to     cause a heap-based buffer overflow condition, resulting     in the execution of arbitrary code.

  - A use-after-free error exists in the unserialize()     function in var.c. An unauthenticated, remote attacker     can exploit this to dereference already freed memory,     resulting in the execution of arbitrary code.

  - A flaw exists in the php_ftp_fopen_connect() function in     ftp_fopen_wrapper.c that allows a man-in-the-middle     attacker to silently downgrade to regular FTP even if a     secure method has been requested.

  - An integer overflow condition exists in the     php_url_encode() function in url.c that occurs when     handling overly long strings. An unauthenticated, remote     attacker can exploit this to corrupt memory, resulting     in the execution of arbitrary code.

  - An integer overflow condition exists in the     php_uuencode() function in uuencode.c. An     unauthenticated, remote attacker can exploit this to     corrupt memory, resulting in the execution of arbitrary     code.

  - An integer overflow condition exists in the     bzdecompress() function in bz2.c. An unauthenticated,     remote attacker can exploit this to corrupt memory,     resulting in the execution of arbitrary code.

  - An integer overflow condition exists in the     curl_escape() function in interface.c that occurs when     handling overly long escaped strings. An     unauthenticated, remote attacker can exploit this to     corrupt memory, resulting in the execution of arbitrary     code.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
