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.
