Versions of PHP 5.5.x prior to 5.5.37, or 5.6.x prior to 5.6.23, or 7.0.x prior to 7.0.8 are vulnerable to the following issues :

 - PHP 'ext/mysqlnd/mysqlnd.c' contains a flaw that is due to the program failing to properly enforce the requirement of an SSL/TLS connection when the '--ssl client' option is used. This may allow a MitM (Man-in-the-Middle) attacker to downgrade the connection to plain HTTP when expected to be HTTPS. (CVE-2015-8838)
 - An integer overflow condition exists in the 'getFromIndex()'' and 'getFromName()' methods of 'ZipArchive'. The issue is triggered as user-supplied input is not properly validated when handling a specially crafted ZIP file. This may allow an attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2016-3078)
 - An XXE (Xml eXternal Entity) injection and expansion flaw affects the 'libxml_disable_entity_loader()' function in the source file 'ext/libxml/libxml.c' in PHP-FPM that is triggered during the parsing of XML data. 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'. 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, causing a denial of service in a process linked against PHP or potentially allowing the execution of arbitrary code.
 - An out-of-bounds read flaw exists within the 'pass2_no_dither()' function inside 'ext/gd/libgd/gd_topal.c' that may allow a remote attacker to crash a process utilizing PHP or potentially disclose memory contents.
 - An integer overflow condition exists in 'ext/standard/string.c'. The issue is triggered as user-supplied input is not properly validated when handling string lengths. This may allow a remote attacker to have an unspecified impact.
 - A double-free flaw exists within the '_php_mb_regex_ereg_replace_exec()' function inside 'ext/mbstring/php_mbregex.c' that is triggered when handling a failed callback execution. This may allow a remote attacker to potentially execute arbitrary code. (CVE-2016-5768)
 - An integer overflow condition exists in 'ext/spl/spl_directory.c'. The issue is triggered by an 'int/size_t' confusion issue. This may allow a remote attacker to have an unspecified impact. (CVE-2016-5770)
 - An integer overflow condition exists in 'ext/mcrypt/mcrypt.c'. The issue is triggered as user-supplied input is not properly validated when handling data values. This may allow a remote attacker to cause a heap-based buffer overflow, resulting in a denial of service in a process linked against PHP or potentially allowing the execution of arbitrary code. (CVE-2016-5769)
 - An integer overflow condition exists within the 'nl2br()' function inside 'ext/standard/string.c'. The issue is triggered as user-supplied input is not properly validated when handling new_length values. This may allow a remote attacker to have an unspecified impact.
 - An integer overflow condition exists within multiple functions in 'ext/standard/string.c'. The issue is triggered as user-supplied input is not properly validated when handling string values. This may allow a remote attacker to have an unspecified impact.
 - A double-free flaw within the 'php_wddx_process_data()' function inside 'ext/wddx/wddx.c' that is triggered during the handling of specially crafted XML content. This may allow a remote attacker to potentially execute arbitrary code. (CVE-2016-5772)
 - An integer overflow condition exists witin the 'gdImagePaletteToTrueColor()' function inside 'ext/gd/libgd/gd.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 in a process linked against PHP or potentially allowing the execution of arbitrary code. (CVE-2016-5767)
 - An invalid free flaw exists within the 'phar_extract_file()' function inside 'ext/phar/phar_object.c'. This may allow a remote attacker to have an unspecified impact. (CVE-2016-4473)
 - An integer overflow condition exists within the '_gd2GetHeader()' function inside 'ext/gd/libgd/gd_gd2.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 in a process linked against PHP or potentially allowing the execution of arbitrary code. (CVE-2016-5766)
