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.

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.

  - ext/wddx/wddx.c in PHP before 5.6.25 and 7.x before     7.0.10 allows remote attackers to cause a denial of     service (NULL pointer dereference and application     crash) or possibly have unspecified other impact via an     invalid wddxPacket XML document that is mishandled in a     wddx_deserialize call, as demonstrated by a stray     element inside a boolean element, leading to incorrect     pop processing.(CVE-2016-7132)

  - The php_wddx_pop_element function in ext/wddx/wddx.c in     PHP before 5.6.25 and 7.x before 7.0.10 allows remote     attackers to cause a denial of service (NULL pointer     dereference and application crash) or possibly have     unspecified other impact via an invalid base64 binary     value, as demonstrated by a wddx_deserialize call that     mishandles a binary element in a wddxPacket XML     documenti1/4Z( CVE-2016-7130)

  - The imagegammacorrect function in ext/gd/gd.c in PHP     before 5.6.25 and 7.x before 7.0.10 does not properly     validate gamma values, which allows remote attackers to     cause a denial of service (out-of-bounds write) or     possibly have unspecified other impact by providing     different signs for the second and third     arguments.(CVE-2016-7127)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The php_wddx_process_data function in ext/wddx/wddx.c in PHP before 5.6.25 and 7.x before 7.0.10 allows     remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other     impact via an invalid ISO 8601 time value, as demonstrated by a wddx_deserialize call that mishandles a     dateTime element in a wddxPacket XML document. (CVE-2016-7129)

Note that Nessus relies on the presence of the package as reported by the vendor.

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.
