According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.29. It is, therefore, affected by multiple vulnerabilities :
A memory corruption issue exists in the php_wddx_push_element() function in ext/wddx/wddx.c that is triggered when decoding empty boolean elements. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9935)
A flaw exists in the in the openssl_pbkdf2() function in ext/openssl/openssl.c that is triggered when handling overly large key length parameters. An unauthenticated, remote attacker can exploit this to cause a denial of service condition.
