The version of PHP running on the remote web server is affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade to PHP version 5.6.29 or later.
