FINAL RESULTS:

data/xml2-0.5/xml2.c:141:3:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
		strcpy(leaf->name,attr ? "@" : "");
data/xml2-0.5/xml2.c:142:3:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
		strcat(leaf->name,name);
data/xml2-0.5/xml2.c:215:2:  [4] (format) vfprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
	vfprintf(stderr,msg,ap);
data/xml2-0.5/2csv.c:39:23:  [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 (EOF != (arg = getopt(argc,argv,"q:d:"))) switch (arg) {
data/xml2-0.5/csv2.c:93:23:  [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 (EOF != (arg = getopt(argc,argv,"fq:d:"))) switch (arg) {
data/xml2-0.5/csv2.c:40:4:  [2] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused). Risk is low because the source is a constant string.
			strcpy(ptr,"field");
data/xml2-0.5/xml2.c:168:2:  [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(content_buffer + content_len,ch,len);
data/xml2-0.5/xml2.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.
	char buffer[4096];
data/xml2-0.5/2csv.c:19:29:  [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 (strcspn(vec[i],d) == strlen(vec[i])) 
data/xml2-0.5/2csv.c:48:15:  [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).
	record_len = strlen((record = argv[0]));
data/xml2-0.5/2csv.c:54:18:  [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).
		field_len[i] = strlen(argv[i]);
data/xml2-0.5/2csv.c:62:10:  [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).
		len += strlen(buffer + len);
data/xml2-0.5/2xml.c:224:16:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	while ((num = read(0,len + buffer,alloc - len)) > 0) {
data/xml2-0.5/csv2.c:108:16:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	while ((num = read(0,len + buffer,alloc - len)) > 0) {
data/xml2-0.5/xml2.c:140:27:  [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).
		leaf->name = malloc(2 + strlen(name));
data/xml2-0.5/xml2.c:182:29:  [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).
		content(atts[1],atts[1] ? strlen(atts[1]) : 0,0);
data/xml2-0.5/xml2.c:206:16:  [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).
	content(value,strlen(value),1);
data/xml2-0.5/xml2.c:264:20:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	while (0 < (num = read(0,buffer,sizeof(buffer)))
