FINAL RESULTS:
data/openzwave-controlpanel-0.2a+git20161006.a390f35/webserver.cpp:341:2: [5] (buffer) strncat:
Easily used incorrectly (e.g., incorrectly computing the correct maximum
size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
or automatically resizing strings. Risk is high; the length parameter
appears to be a constant, instead of computing the number of characters
left.
strncat(fntemp, ".xml", sizeof(fntemp));

and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.

Some older implementations do not protect against internal buffer overflows
(CWE-120, CWE-20). Check implementation on installation, or limit the size
of all string inputs.

Environment variables are untrustable input if they can be set by an
attacker. They can have any content and length, and the same variable can
be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.

force the opening of special file type (e.g., device files), move things
around to create a race condition, control its ancestors, or change its
contents? (CWE-362).
