FINAL RESULTS:

data/postgresql-q3c-2.0.0/q3cube.c:2971:4:  [4] (format) fprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
			fprintf(stdout,Q3C_COORD_FMT" "Q3C_COORD_FMT" "Q3C_COORD_FMT" "Q3C_COORD_FMT" "Q3C_COORD_FMT" "Q3C_COORD_FMT"\n", axx,ayy,axy,ax,ay,a);
data/postgresql-q3c-2.0.0/common.h:326:12:  [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 *too_large,
data/postgresql-q3c-2.0.0/gen_data.c:74:16:  [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).
		rand_state = atoi(argv[1]);
data/postgresql-q3c-2.0.0/gen_data.c:76:13:  [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).
		npoints = atoi(argv[2]);
data/postgresql-q3c-2.0.0/q3c.c:980:2:  [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.

data/postgresql-q3c-2.0.0/q3c_poly.c:347:36:  [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 *too_large,
data/postgresql-q3c-2.0.0/q3cube.c:1314:13:  [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(filename, "w");
data/postgresql-q3c-2.0.0/q3cube.c:2357:4:  [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(work_stack + (*work_nstack - tmp_stack1),
data/postgresql-q3c-2.0.0/q3cube.c:2364:4:  [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(work_stack + (*work_nstack - tmp_stack1), 
data/postgresql-q3c-2.0.0/q3cube.c:128:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
	strncpy(out,__q3c_version,maxchar);
