Examining data/xf86-input-xwiimote-0.5/src/xwiimote.c

FINAL RESULTS:

data/xf86-input-xwiimote-0.5/src/xwiimote.c:1253:9:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
	*out = atoi(t);
data/xf86-input-xwiimote-0.5/src/xwiimote.c:1310:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	memcpy(dev->map_key, map_key_default, sizeof(map_key_default));
