FINAL RESULTS:

data/libalgorithm-svm-perl-0.13/bindings.cpp:9:2:  [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(stdout,a,alist);
data/libalgorithm-svm-perl-0.13/libsvm.cpp:42:2:  [4] (format) vprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
	vprintf(fmt,ap);
data/libalgorithm-svm-perl-0.13/bindings.cpp:39:2:  [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(address,attributes,sizeof(struct svm_node)*(n+1));
data/libalgorithm-svm-perl-0.13/bindings.cpp:50:3:  [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(address,attributes,sizeof(struct svm_node)*(n+1));
data/libalgorithm-svm-perl-0.13/libsvm.cpp:21:2:  [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((void *)dst,(void *)src,sizeof(T)*n);
data/libalgorithm-svm-perl-0.13/libsvm.cpp:2620:13:  [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");

  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,"r");
data/libalgorithm-svm-perl-0.13/libsvm.cpp:2720:2:  [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 cmd[81];
data/libalgorithm-svm-perl-0.13/libsvm.cpp:2723:3:  [1] (buffer) fscanf:
  It's unclear if the %s limit in the format string is small enough
  (CWE-120). Check that the limit is sufficiently small, or use a different
  input function.
		fscanf(fp,"%80s",cmd);
data/libalgorithm-svm-perl-0.13/libsvm.cpp:2727:4:  [1] (buffer) fscanf:
  It's unclear if the %s limit in the format string is small enough
  (CWE-120). Check that the limit is sufficiently small, or use a different
  input function.
			fscanf(fp,"%80s",cmd);
data/libalgorithm-svm-perl-0.13/libsvm.cpp:2749:4:  [1] (buffer) fscanf:
  It's unclear if the %s limit in the format string is small enough
  (CWE-120). Check that the limit is sufficiently small, or use a different
  input function.
			fscanf(fp,"%80s",cmd);
data/libalgorithm-svm-perl-0.13/libsvm.cpp:2818:13:  [1] (buffer) getc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
				int c = getc(fp);
data/libalgorithm-svm-perl-0.13/libsvm.cpp:2841:11:  [1] (buffer) fgetc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
		int c = fgetc(fp);
data/libalgorithm-svm-perl-0.13/libsvm.cpp:2878:9:  [1] (buffer) getc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
				c = getc(fp);
