host is older than 5.2.6.  Such versions may be affected by the
following issues :

  - A stack-based buffer overflow in FastCGI SAPI.

  - An integer overflow in printf().

  - An security issue arising from improper calculation
    of the length of PATH_TRANSLATED in cgi_main.c.

  - A safe_mode bypass in cURL.

  - Incomplete handling of multibyte chars inside
    escapeshellcmd().

  - Issues in the bundled PCRE fixed by version 7.6.");
