FINAL RESULTS:

data/acpi-support-0.143/debian/addons/fakekey/acpi_fakekey.c:16:8:  [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).
	key = atoi(argv[1]);
data/acpi-support-0.143/debian/addons/fakekey/acpi_fakekey.c:18:12:  [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).
	if ((fd = open(FIFO, O_WRONLY)) == -1) {
data/acpi-support-0.143/debian/addons/fakekey/acpi_fakekeyd.c:33:15:  [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).
		if ((fifo = open(FIFO, O_RDWR | O_NONBLOCK)) == -1)
data/acpi-support-0.143/debian/addons/fakekey/acpi_fakekeyd.c:45:9:  [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).
	udev = open("/dev/uinput", O_WRONLY | O_NDELAY);
data/acpi-support-0.143/debian/addons/fakekey/acpi_fakekeyd.c:52:2:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120). Risk is low because the source is a
  constant string.
	strncpy(dev.name, "ACPI Virtual Keyboard Device", UINPUT_MAX_NAME_SIZE);
data/acpi-support-0.143/debian/addons/fakekey/acpi_fakekeyd.c:94:7:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
		n = read(fifo, &key, 1);
