FINAL RESULTS:

data/icu-ext-1.6.1/icu_break.c:92:3:  [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(ctxt->source_text, VARDATA_ANY(txt), ctxt->len);
data/icu-ext-1.6.1/icu_ext.c:51:2:  [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 buf[U_MAX_VERSION_STRING_LENGTH+1];
data/icu-ext-1.6.1/icu_ext.c:63:2:  [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 buf[U_MAX_VERSION_STRING_LENGTH+1];
data/icu-ext-1.6.1/icu_ext.c:289:3:  [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 buf[U_MAX_VERSION_STRING_LENGTH+1];
data/icu-ext-1.6.1/icu_ext.c:472:2:  [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 buf[1024];
data/icu-ext-1.6.1/icu_ext.c:750:2:  [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 local_buf[80];
data/icu-ext-1.6.1/icu_transform.c:130:2:  [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(original, utext, (ulen+1)*sizeof(UChar));
data/icu-ext-1.6.1/icu_transform.c:169:5:  [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(utext, original, (ulen+1)*sizeof(UChar));
data/icu-ext-1.6.1/icu_transform.c:106:47:  [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).
		in_ulen = icu_to_uchar(&trans_id, input_id, strlen(input_id));
