Examining data/gxmessage-3.4.3/gxmessage.c

FINAL RESULTS:

data/gxmessage-3.4.3/gxmessage.c:268:11:  [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).
		value = atoi (++colon);
data/gxmessage-3.4.3/gxmessage.c:244:27:  [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).
			memmove (str, str + 1, strlen (str));
data/gxmessage-3.4.3/gxmessage.c:333:8:  [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).
	len = strlen (str);
data/gxmessage-3.4.3/gxmessage.c:512:50:  [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).
	gtk_text_buffer_set_text (buf, gx.message_text, strlen (gx.message_text));
data/gxmessage-3.4.3/gxmessage.c:680:16:  [1] (buffer) getc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	while ( (ch = getc (stdin)) != EOF ) {
data/gxmessage-3.4.3/gxmessage.c:738:9:  [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).
		len = strlen (s);
data/gxmessage-3.4.3/gxmessage.c:1010:20:  [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).
		gx.message_len = strlen (tmpstr);
