Examining data/ocaml-mad-0.4.6/src/mad_stubs.c

FINAL RESULTS:

data/ocaml-mad-0.4.6/src/mad_stubs.c:170:14:  [2] (buffer) MultiByteToWideChar:
  Requires maximum length in CHARACTERS, not bytes (CWE-120).
  int size = MultiByteToWideChar(CP_UTF8, 0, fname, -1, NULL, 0);
data/ocaml-mad-0.4.6/src/mad_stubs.c:178:7:  [2] (buffer) MultiByteToWideChar:
  Requires maximum length in CHARACTERS, not bytes (CWE-120).
  if (MultiByteToWideChar(CP_UTF8, 0, fname, -1, wfname, size) == 0)
data/ocaml-mad-0.4.6/src/mad_stubs.c:188:14:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
  FILE *fd = fopen(String_val(file), "rb");
data/ocaml-mad-0.4.6/src/mad_stubs.c:197:3:  [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 id3_header[3];
data/ocaml-mad-0.4.6/src/mad_stubs.c:383:9:  [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(read_start, String_val(Field(data, 0)), read_size);
data/ocaml-mad-0.4.6/src/mad_stubs.c:261:44:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
CAMLprim value ocaml_mad_skip_id3tag(value read, value seek, value tell)
data/ocaml-mad-0.4.6/src/mad_stubs.c:263:14:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  CAMLparam3(read,seek,tell);
data/ocaml-mad-0.4.6/src/mad_stubs.c:281:23:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  ret = caml_callback(read,Val_int(3)); 
data/ocaml-mad-0.4.6/src/mad_stubs.c:292:25:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    ret = caml_callback(read,Val_int(3));
data/ocaml-mad-0.4.6/src/mad_stubs.c:303:25:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    ret = caml_callback(read,Val_int(sizeof(uint32_t)));
