FINAL RESULTS:

data/ibus-m17n-1.4.3/src/m17nutil.c:303:34:  [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).
            cnode->config.rank = atoi (sub_node->text);
data/ibus-m17n-1.4.3/src/engine.c:647:16:  [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).
    if (buf && strlen (buf)) {
data/ibus-m17n-1.4.3/src/engine.c:965:23:  [1] (buffer) strlen:
