"According to its banner, the version of PHP running on the remote host
is 5.5.x prior to 5.5.31 or 5.6.x prior to 5.6.17. It is, therefore,
affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in the
    gdImageRotateInterpolated() function in file
    gd_interpolation.c when handling background colors.
    A remote attacker can exploit this to disclose memory
    contents or crash the application. (CVE-2016-1903)

  - An unspecified flaw exists in file fpm_log.c in the
    fpm_log_write() function when handling very long
    HTTP requests. A local attacker can exploit this to
    obtain sensitive information, via access to the
    access log file. (CVE-2016-5114)

  - A use-after-free error exists in file wddx.c in the
    php_wddx_pop_element() function when handling WDDX
    packet deserialization. A remote attacker can exploit
    this, by dereferencing already freed memory, to execute
    arbitrary code.

  - A type confusion flaw exists in file xmlrpc-epi-php.c
    in the PHP_to_XMLRPC_worker() function. A remote
    attacker can exploit this to disclose memory contents,
    crash the application process, or have other impact.

  - A type confusion flaw exists in file wddx.c when
    handling WDDX packet deserialization. A remote attacker
    can exploit this to execute arbitrary code.

  - A flaw exists in file lsapilib.c when handling requests
    due to the LSAPI module failing to clear its secrets in
    child processes. A remote attacker can exploit this to
    gain access to memory contents, resulting in the
    disclosure of sensitive information.

  - A flaw exists in file lsapilib.c in the parseRequest()
    function due to a failure to properly sanitize input
    passed through multiple, unspecified parameters. A
    remote attacker can exploit this to cause a denial of
    service.");
