FINAL RESULTS:

data/gnome-sushi-3.34.0/src/libsushi/sushi-font-widget.c:297:12:  [3] (random) g_random_int_range:
  This function is not sufficiently random for security-related functions
  such as key and nonce creation (CWE-327). Use a more secure technique for
  acquiring random values.
    rand = g_random_int_range (0, total_chars);
data/gnome-sushi-3.34.0/src/libsushi/externalwindow.c:56:53:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
          const char *x11_handle_str = handle_str + strlen (x11_prefix);
data/gnome-sushi-3.34.0/src/libsushi/externalwindow.c:69:57:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
          const char *wayland_handle_str = handle_str + strlen (wayland_prefix);
data/gnome-sushi-3.34.0/src/libsushi/sushi-font-widget.c:116:49:  [1] (buffer) strlen:
