Examining data/mbw-1.2.2/mbw.c

FINAL RESULTS:

data/mbw-1.2.2/mbw.c:186:14:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
    while((o=getopt(argc, argv, "haqn:t:b:")) != EOF) {
data/mbw-1.2.2/mbw.c:104:9:  [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(b, a, array_bytes);
