FINAL RESULTS:

data/libsoldout-1.4/buffer.c:286:6:  [4] (format) vsnprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
	n = vsnprintf(buf->data + buf->size, buf->asize - buf->size, fmt, ap);

  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
		n = vsnprintf (buf->data + buf->size,
data/libsoldout-1.4/buffer.h:75:26:  [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.

data/libsoldout-1.4/mkd2html.c:82:12:  [3] (buffer) getopt_long:
  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.
	    (ch = getopt_long(argc, argv, "dHhmnx", longopts, 0)) != -1)

  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
	    (ch = getopt_long(argc, argv, "d:hs:t:", longopts, 0)) != -1)
data/libsoldout-1.4/benchmark.c:69:10:  [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).
				nb = atoi(argv[i] + 2);
data/libsoldout-1.4/benchmark.c:90:9:  [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).
			in = fopen(argv[f], "r");
data/libsoldout-1.4/buffer.c:125:2:  [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(ret->data, src->data, src->size);
data/libsoldout-1.4/buffer.c:192:2:  [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(buf->data + buf->size, data, len);

  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).

  contents? (CWE-362).
		in = fopen(argv[1], "r");
data/libsoldout-1.4/mkd2man.c:236:2:  [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.

data/libsoldout-1.4/buffer.c:92:21:  [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).
	const size_t len = strlen(b);
data/libsoldout-1.4/buffer.c:199:19:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may

data/libsoldout-1.4/mkd2man.c:320:18:  [1] (buffer) strlen:
