Integer overflow in the str_pad function in ext/standard/string.c in PHP before 7.0.4 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a long string, leading to a heap-based buffer overflow.

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.4. It is, therefore, affected by multiple vulnerabilities :

 - A type confusion error exists in file ext/soap/php_http.c in the make_http_soap_request() function when handling cookie data. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-3185)

 - Multiple integer overflow conditions exist in file ext/xml/xml.c in the xml_utf8_encode functions due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these to cause a heap-based buffer overflow, resulting in a denial of service or the execution of arbitrary code. (CVE-2016-4344)

 - An integer overflow condition exists in the php_filter_encode_url() function due to improper validation of user-supplied input. A remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service or th execution of arbitrary code. (CVE-2016-4345)

 - An overflow condition exists in the xml_utf8_encode functions due to improper validation of user-supplied input. A 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-2016-4346)

 - A flaw exists when handling the third call while running function.forward-static-call.php. An unauthenticated, remote attacker can exploit this to cause a denial of service by crashing the interpreter.

 - An integer overflow condition exists in file ext/standard/string.c in the php_implode() function due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service or the execution of arbitrary code.

 - An integer overflow condition exists in file ext/standard/string.c in the zend_string_alloc() function due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to execute arbitrary code.

 - A stack corruption issue exists when handling certain Magento2 commands that allows an unauthenticated, remote attacker to cause a denial of service.

 - A flaw exists in file sapi/cli/php_cli_server.c due to the built-in HTTP server not properly restricting file requests. An unauthenticated, remote attacker can exploit this to access arbitrary files.

 - A use-after-free error exists in Zend Opcache when updating cached directory names that have been cached in the current working directory. An unauthenticated, remote attacker can exploit this to deference already freed memory, resulting in the execution of arbitrary code.

 - A NULL pointer dereference flaw exists in file ext/zip/php_zip.c in the Zip::ExtractTo() method that allows an unauthenticated, remote attacker to cause a denial of service.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

The issue is due to an incorrectly configured XML parser accepting XML external entities from an untrusted source. By sending specially crafted XML data, a remote attacker can gain access to sensitive information or cause a denial of service. (CVE-2015-8866)
 - An integer overflow condition exists in the 'php_filter_encode_url()' function in 'ext/filter/sanitizing_filters.c'. The issue is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2016-4345)
 - An integer overflow condition exists in 'ext/standard/string.c'. The issue is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2016-4346)
 - The program contains an out-of-bounds read flaw in 'ext/intl/grapheme/grapheme_string.c' that is triggered when handling negative offsets in 'zif_grapheme_stripos'. This may allow a remote attacker to crash a process utilizing the language or potentially disclose memory contents. (CVE-2016-4540, CVE-2016-4541)
 - An out-of-bounds read flaw exists in the 'php_str2num()' function in 'ext/bcmath/bcmath.c' that is triggered when accepting negative scales. This may allow a remote attacker to crash a process utilizing the language or potentially disclose memory contents. (CVE-2016-4537, CVE-2016-4538)
 - An out-of-bounds read flaw exists in the 'exif_read_data()' function in 'ext/exif/exif.c' that is triggered when handling exif headers. This may allow a remote attacker to crash a process utilizing the language or potentially disclose memory contents. (CVE-2016-4542, CVE-2016-4543, CVE-2016-4544)
 - A flaw in the 'xml_parse_into_struct()' function in 'ext/xml/xml.c' is triggered during the handling of a specially crafted XML content. This may allow a remote attacker to cause a denial of service. (CVE-2016-4539)
 - A double-free flaw exists in the 'php_formatted_print()' function in 'ext/standard/formatted_print.c'. This may allow an attacker to have an unspecified impact. (CVE-2015-8880)
 - A flaw exists in 'main/php_open_temporary_file.c' that is triggered as thread safety is not ensured during the handling of temporary directories. This may allow a remote attacker to cause a denial of service. (CVE-2015-8878)
 - An integer overflow flaw exists in the 'php_html_entities()' and 'php_filter_full_special_chars()' functions in 'ext/standard/html.c' that is triggered as input is not properly validated. This may allow a remote attacker to have an unspecified impact. No further details have been provided. (CVE-2016-5094, CVE-2016-5095)
 - An integer underflow issue exists in 'ext/standard/file.c' that is triggered as input is not properly validated. This may allow a remote attacker to cause a NULL write and cause a process linked against PHP to crash. (CVE-2016-5096)
 - An out-of-bounds read flaw exists in the '_gdContributionsCalc()' function in 'ext/gd/libgd/gd_interpolation.c'. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents. (CVE-2013-7456)
 - An out-of-bounds read flaw exists in the 'get_icu_value_internal()' function within 'ext/intl/locale/locale_methods.c' that is triggered when handling user-supplied input. This may allow a remote attacker to crash a process linked against the library or potentially disclose memory contents. (CVE-2016-5093)
 - A flaw exists that allows a cross-site scripting (XSS) attack. This flaw exists because the 'header()' function does not filter input passed via HTTP headers before returning it to users. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2015-8935)
 - A use-after-free error exists in the garbage collection algorithm in 'ext/zip/php_zip.c'. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-5773)
 - An integer overflow condition exists in the 'json_decode()' and 'json_utf8_to_utf16()' functions in 'ext/standard/php_smart_str.h'.
