FINAL RESULTS:

data/r-cran-e1071-1.7-4/src/Rsvm.c:272:2:  [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(*error, s);
data/r-cran-e1071-1.7-4/src/svm.cpp:59:2:  [4] (format) vsprintf:
  Potential format string problem (CWE-134). Make format string constant.
	vsprintf(buf,fmt,ap);
data/r-cran-e1071-1.7-4/src/svm.cpp:2782:48:  [4] (buffer) fscanf:
  The scanf() family's %s operation, without a limit specification, permits
  buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
  different input function. If the scanf format is influenceable by an
  attacker, it's exploitable.

	    memcpy (nSV, model->nSV, *nclasses * sizeof(int));
data/r-cran-e1071-1.7-4/src/Rsvm.c:369:7:  [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 (m.sv_coef[i], coefs + i*m.l, m.l * sizeof (double));

	memcpy((void *)dst,(void *)src,sizeof(T)*n);
data/r-cran-e1071-1.7-4/src/svm.cpp:56:2:  [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[BUFSIZ];
data/r-cran-e1071-1.7-4/src/svm.cpp:2659:13:  [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 *fp = fopen(model_file_name,"w");
data/r-cran-e1071-1.7-4/src/svm.cpp:2791:2:  [2] (buffer) char:
