FINAL RESULTS:

data/r-cran-fnn-1.1.3/src/include/ANN/ANN.h:130:13:  [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.
    #define printf Rprintf
data/r-cran-fnn-1.1.3/src/label_point.h:13:13:  [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.
    #define printf Rprintf
data/r-cran-fnn-1.1.3/src/KNN_cover_test.cpp:51:12:  [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).
   int k = atoi(argv[1]);
data/r-cran-fnn-1.1.3/src/kd_dump.cpp:265:2:  [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 str[STRING_LEN];						// storage for string
data/r-cran-fnn-1.1.3/src/kd_dump.cpp:266:2:  [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 version[STRING_LEN];					// ANN version number
data/r-cran-fnn-1.1.3/src/kd_dump.cpp:374:2:  [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 tag[STRING_LEN];						// tag (leaf, split, shrink)
data/r-cran-fnn-1.1.3/src/label_point.h:51:17:  [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 *input = fopen(filename,"r");
data/r-cran-fnn-1.1.3/src/label_point.h:85:7:  [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(new_p, p.elements,sizeof(P)*p.index);
data/r-cran-fnn-1.1.3/src/label_point.h:62:16:  [1] (buffer) getc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  while ( (c = getc(input)) != EOF )
data/r-cran-fnn-1.1.3/src/label_point.h:66:19:  [1] (buffer) getc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
      while ((c = getc(input)) != '\n' )
data/r-cran-fnn-1.1.3/src/label_point.h:71:10:  [1] (buffer) getc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	    c = getc(input);
