FINAL RESULTS:

data/toilet-0.3/src/main.c:156:13:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
            printf(MOREINFO, argv[0]);
data/toilet-0.3/src/main.c:160:13:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
            printf(MOREINFO, argv[0]);
data/toilet-0.3/src/figlet.c:39:5:  [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 path[2048];
data/toilet-0.3/src/main.c:90:24:  [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).
            infocode = atoi(caca_optarg);
data/toilet-0.3/src/main.c:114:30:  [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).

            char buf[7];
data/toilet-0.3/src/filter.c:86:49:  [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(!strncmp(filter, lookup[i].name, strlen(lookup[i].name)))
data/toilet-0.3/src/filter.c:88:21:  [1] (buffer) strlen:
