According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.27. It is, therefore, affected by multiple vulnerabilities :

  - A NULL pointer dereference flaw exists in the     SimpleXMLElement::asXML() function within file     ext/simplexml/simplexml.c. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition.

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

  - A flaw exists in the openssl_random_pseudo_bytes()     function within file ext/openssl/openssl.c when handling     strings larger than 2GB. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition.

  - A flaw exists in the openssl_encrypt() function within     file ext/openssl/openssl.c when handling strings larger     than 2GB. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition.

  - An integer overflow condition exists in the     imap_8bit() function within file ext/imap/php_imap.c due     to improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code.

  - A flaw exists in the _bc_new_num_ex() function within     file ext/bcmath/libbcmath/src/init.c when handling     values passed via the 'scale' parameter. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition.

  - A flaw exists in the php_resolve_path() function within     file main/fopen_wrappers.c when handling negative size     values passed via the 'filename' parameter. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition.

  - A flaw exists in the dom_document_save_html() function     within file ext/dom/document.c due to missing NULL     checks. An unauthenticated, remote attacker can exploit     this to cause a denial of service condition.

  - A use-after-free error exists in the unserialize()     function that allows an unauthenticated, remote attacker     to dereference already freed memory, resulting in the     execution of arbitrary code.

  - An integer overflow condition exists in the     mb_encode_*() functions in file ext/mbstring/mbstring.c     due to improper validation of the length of encoded     data. An unauthenticated, remote attacker can exploit     this to cause a denial of service condition or the     execution of arbitrary code.

  - A NULL pointer dereference flaw exists in the     CachingIterator() function within file     ext/spl/spl_iterators.c when handling string     conversions. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition.

  - An integer overflow condition exists in the     number_format() function within file ext/standard/math.c     when handling 'decimals' and 'dec_point' parameters that     have values that are equal or close to 0x7fffffff. An     unauthenticated, remote attacker can exploit this to     cause a heap buffer overflow, resulting in a denial of     service condition or the execution of arbitrary code.

  - A stack-based overflow condition exists in the     ResourceBundle::create and ResourceBundle::getLocales     methods and their respective functions within file     ext/intl/resourcebundle/resourcebundle_class.c due to     improper validation of input passed via the 'bundlename'     parameter. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     the execution or arbitrary code.

  - An integer overflow condition exists in the     php_pcre_replace_impl() function within file     ext/pcre/php_pcre.c 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 condition or the     execution of arbitrary code.
