FINAL RESULTS:

data/windowlab-1.40/menufile.c:57:14:  [5] (race) readlink:
  This accepts filename arguments; if an attacker can move those files or
  change the link content, a race condition results. Also, it does not
  terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
		if ((len = readlink("/proc/self/exe", menurcpath, PATH_MAX - 1)) == -1)
data/windowlab-1.40/menufile.c:109:7:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
						strcpy(menuitems[num_menuitems].label, labelstr);
data/windowlab-1.40/menufile.c:110:7:  [4] (buffer) strcpy:

data/windowlab-1.40/misc.c:65:4:  [4] (shell) execlp:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
			execlp(envshell, envshellname, "-c", cmd, NULL);
data/windowlab-1.40/misc.c:309:2:  [4] (format) snprintf:

  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).
