Examining data/dbar-0.0.20100524/dbar.c

FINAL RESULTS:

data/dbar-0.0.20100524/dbar.c:135:2:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
	char aval[MAXLEN], *endptr;
data/dbar-0.0.20100524/dbar.c:149:16:  [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).
				maxchars = atoi(argv[i]);
