remote code execution vulnerability.");

"According to its banner, the version of PHP running on the remote web
server is 7.0.x prior to 7.0.14. It is, therefore, affected by the
following vulnerabilities:

  -  A remote code execution vulnerability due to a memory
     corruption issue in the php_wddx_push_element()
     function in ext/wddx/wddx.c that occurs 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 deserialization vulnerability exists in the
    ext/standard/var.c script. An unauthenticated, remote
    attacker can exploit this, via crafted serialized data,
    to the application to stop responding or execute
    arbitrary code on the target host. (CVE-2016-9936)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
