multiple vulnerabilities.");
  script_set_attribute(attribute:"description", value:
"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 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
     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.
     (CVE-2016-7133)

  - 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. (CVE-2016-7134)");
