FINAL RESULTS:

data/gkrellm-thinkbat-0.2.2/collect_data.c:44:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(file, "%s%s%s", SMAPI_PATH, BATTERY, DESIGN_CAPACITY);
data/gkrellm-thinkbat-0.2.2/collect_data.c:47:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(file, "%s%s%s", SMAPI_PATH, BATTERY, REMAINING_CAPACITY);
data/gkrellm-thinkbat-0.2.2/collect_data.c:50:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(file, "%s%s%s", SMAPI_PATH, BATTERY, POWER_NOW);
data/gkrellm-thinkbat-0.2.2/collect_data.c:53:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(file, "%s%s%s", SMAPI_PATH, BATTERY, POWER_AVG);
data/gkrellm-thinkbat-0.2.2/collect_data.c:56:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(file, "%s%s%s", SMAPI_PATH, BATTERY, LAST_FULL);
data/gkrellm-thinkbat-0.2.2/collect_data.c:59:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(file, "%s%s", SMAPI_PATH, AC);
data/gkrellm-thinkbat-0.2.2/collect_data.c:129:2:  [4] (buffer) sscanf:
  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.
	sscanf(buff, "%d %s", &data, dump);
data/gkrellm-thinkbat-0.2.2/collect_data.c:42:2:  [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 file[FILE_LEN];
data/gkrellm-thinkbat-0.2.2/collect_data.c:116:2:  [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 buff[BUF_LEN], dump[10];
data/gkrellm-thinkbat-0.2.2/collect_data.c:118:7:  [2] (misc) open:
  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).
	fd = open(file, O_RDONLY);
data/gkrellm-thinkbat-0.2.2/collect_data.c:123:5:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	if(read(fd, buff, BUF_LEN) <= 0) {
data/gkrellm-thinkbat-0.2.2/gkrellm-thinkbat.c:159:6:  [1] (buffer) sscanf:
  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.
	if (sscanf(arg, "%31s %[^\n]", config, item) == 2) {
