According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.10. It is, therefore, affected by multiple vulnerabilities :

 - An overflow condition exists in the curl_escape() function in interface.c due to improper handling of overly long strings. An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.

 - An integer overflow condition exists in the zend_mm_realloc_heap() function in zend_alloc.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.

Note that this software is reportedly affected by other vulnerabilities as well that have not been fixed yet in version 7.0.13.

The remote host is affected by the vulnerability described in GLSA-201611-22 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the       CVE identifiers referenced below for details.
  Impact :

    An attacker can possibly execute arbitrary code or create a Denial of       Service condition.
  Workaround :

    There is no known workaround at this time.

New php packages are available for Slackware 14.0, 14.1, 14.2, and
-current to fix security issues.

Versions of PHP 5.6.x prior to 5.6.25 and 7.0.x prior to 7.0.10 are vulnerable to the following issues :

 - An uninitialized memory use flaw exists in the 'openssl_seal()' method. This may allow a remote attacker to potentially execute arbitrary code.
 - A use-after-free error exists in 'SPL_METHOD(SplObjectStorage)' in 'ext/spl/spl_observer.c'. The issue is triggered when handling unserialize calls. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code.
 - A flaw exists related to certificate validation in the 'ftp_ssl_connect()' function. The issue is due to the server hostname not being verified to match a domain name in the 'Subject's Common Name' (CN) or 'SubjectAltName' field of the X.509 certificate. By spoofing the TLS/SSL server via a certificate that appears valid, an attacker with the ability to intercept network traffic (e.g. MitM, DNS cache poisoning) can disclose and optionally manipulate transmitted data.
 - An overflow condition exists in the 'curl_escape()' function in 'ext/curl/interface.c' that is triggered when handling overly long strings. This may allow a remote attacker to cause a heap-based buffer overflow, resulting in a crash or potentially allowing the execution of arbitrary code.
 - A flaw exists in the 'object_common2()' function in 'ext/standard/var_unserializer.c' that is triggered when handling objects during unserialization. This may allow a remote attacker to potentially execute arbitrary code.
 - An integer overflow condition exists in the 'php_snmp_parse_oid()' function in 'ext/snmp/snmp.c'. This may allow a remote attacker to cause a heap-based buffer overflow and potentially execute arbitrary code.
 - An integer truncation flaw exists in the 'select_colors()' function in 'ext/gd/libgd/gd_topal.c' that is triggered when handling the number of colors. This may allow a remote attacker to cause a heap-based buffer overflow and potentially execute arbitrary code.
 - An integer overflow condition exists in the 'sql_regcase()' function in 'ext/ereg/ereg.c' that is triggered when handling overly long strings. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - A NULL pointer dereference flaw exists in the 'php_wddx_pop_element()' function in 'ext/wddx/wddx.c' that is triggered during the handling of Base64 binary values. This may allow a remote attacker to cause a denial of service.
 - A NULL pointer dereference flaw exists in the 'php_wddx_pop_element()' function in 'ext/wddx/wddx.c'. This may allow a remote attacker to cause a denial of service.
 - An integer overflow condition exists in the 'php_base64_encode()' function in 'ext/standard/base64.c' that is triggered when handling overly long strings. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - A NULL pointer dereference flaw exists in the 'php_wddx_deserialize_ex()' function in 'ext/wddx/wddx.c' that is triggered during the handling of invalid XML content. This may allow a remote attacker to cause a denial of service.
 - An integer overflow condition exists in the 'php_quot_print_encode()' function in 'ext/standard/quot_print.c' that is triggered when handling overly long strings. This may allow a remote attacker to cause a heap-based buffer overflow and potentially execute arbitrary code.
 - A use-after-free error exists in the 'unserialize()' function in 'ext/standard/var.c'. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code.
 - A flaw exists in the 'php_ftp_fopen_connect()' function in 'ext/standard/ftp_fopen_wrapper.c' as it may silently downgrade to regular FTP even if a secure method has been requested. This may allow a Man-in-the-Middle (MitM) attacker to downgrade the FTP communication.
 - A flaw exists in the 'php_wddx_process_data()' function in 'ext/wddx/wddx.c' that is triggered when deserializing invalid dateTime values. This may allow a remote attacker to cause a crash.
 - A flaw exists in the 'exif_process_IFD_in_TIFF()' function in 'ext/exif/exif.c' that is triggered when handling TIFF image content. This may allow a remote attacker to disclose memory contents.
 - An integer overflow condition exists in the 'php_url_encode()' function in 'ext/standard/url.c' that is triggered when handling overly long strings. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - An integer overflow condition exists in the 'php_uuencode()' function in 'ext/standard/uuencode.c'. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - An integer overflow condition exists in the 'bzdecompress()' function in 'ext/bz2/bz2.c'. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - An integer overflow condition exists in the 'zend_mm_realloc_heap()' function in 'Zend/zend_alloc.c' that is triggered as certain input is not properly validated. This may allow a remote attacker to cause a buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
 - An array indexing flaw exists in the 'imagegammacorrect()' function in 'ext/gd/gd.c' that is triggered when handling negative gamma values. This may allow a remote attacker to write a NULL to an arbitrary memory location, causing a crash or potentially allowing the execution of arbitrary code.
 - An integer overflow condition exists in the 'curl_escape()' function in 'ext/curl/interface.c' that is triggered when handling overly long escaped strings. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in 'ext/session/session.c' that is triggered when handling session names. This may allow a remote attacker to inject arbitrary data into sessions.
