FINAL RESULTS:

data/gemdropx-0.9/gemdropx.c:644:7:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
      sprintf(file, "%s/images/%s.bmp", DATA_PREFIX, object_filenames[i]);
data/gemdropx-0.9/gemdropx.c:753:9:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
        sprintf(file, "%s/sounds/%s.wav", DATA_PREFIX, sound_filenames[i]);
data/gemdropx-0.9/gemdropx.c:770:6:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	    sprintf(file, "%s/sounds/%s", DATA_PREFIX, music_filenames[i]);
data/gemdropx-0.9/gemdropx.c:719:3:  [3] (random) srand:
  This function is not sufficiently random for security-related functions
  such as key and nonce creation (CWE-327). Use a more secure technique for
  acquiring random values.
  srand(SDL_GetTicks());
data/gemdropx-0.9/gemdropx.c:2669:8:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
  if ( getenv("HOME" ) != NULL )
data/gemdropx-0.9/gemdropx.c:2672:61:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
      snprintf(datafile,sizeof(datafile)-1, "%s/.gemdropx", getenv("HOME"));
data/gemdropx-0.9/gemdropx.c:126:1:  [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 * object_filenames[NUM_OBJECTS] = {"block", "yellowgem",
data/gemdropx-0.9/gemdropx.c:160:1:  [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 * sound_filenames[NUM_SOUNDS] = {
data/gemdropx-0.9/gemdropx.c:175:1:  [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 * music_filenames[NUM_MODS] = {
data/gemdropx-0.9/gemdropx.c:503:3:  [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 file[128];
data/gemdropx-0.9/gemdropx.c:790:3:  [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 temp[11];
data/gemdropx-0.9/gemdropx.c:794:3:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
  sprintf(temp, "%-10u", num);
data/gemdropx-0.9/gemdropx.c:2562:3:  [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 datafile[1024];
data/gemdropx-0.9/gemdropx.c:2675:8:  [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).
  fi = fopen(datafile, "r");
data/gemdropx-0.9/gemdropx.c:2718:8:  [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).
  fi = fopen(datafile, "w");
data/gemdropx-0.9/gemdropx.c:407:3:  [1] (obsolete) usleep:
  This C routine is considered obsolete (as opposed to the shell command by
  the same name). The interaction of this function with SIGALRM and other
  timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
  unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
  usleep(ms * 1000);
