Examining data/aseqjoy-0.0.2/aseqjoy.c
FINAL RESULTS:
data/aseqjoy-0.0.2/aseqjoy.c:68:2: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf(port_name , "%s Output", client_name);
data/aseqjoy-0.0.2/aseqjoy.c:211:9: [3] (buffer) getopt:
Some older implementations do not protect against internal buffer overflows
(CWE-120, CWE-20). Check implementation on installation, or limit the size
of all string inputs.
int i=getopt(argc, argv, "vhrd:0:1:2:3:");
data/aseqjoy-0.0.2/aseqjoy.c:61:2: [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 client_name[32];
data/aseqjoy-0.0.2/aseqjoy.c:62:2: [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 port_name[48];
data/aseqjoy-0.0.2/aseqjoy.c:67:2: [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(client_name, "Joystick%i", joystick_no);
data/aseqjoy-0.0.2/aseqjoy.c:96:2: [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 device[256];
data/aseqjoy-0.0.2/aseqjoy.c:97:2: [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 name[NAME_LENGTH] = "Unknown";
data/aseqjoy-0.0.2/aseqjoy.c:99:2: [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(device, "/dev/js%i", joystick_no);
data/aseqjoy-0.0.2/aseqjoy.c:101:16: [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 ((joy_fd = open(device, O_RDONLY)) < 0) {
data/aseqjoy-0.0.2/aseqjoy.c:103:3: [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(device, "/dev/input/js%i", joystick_no);
data/aseqjoy-0.0.2/aseqjoy.c:105:17: [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 ((joy_fd = open(device, O_RDONLY)) < 0) {
data/aseqjoy-0.0.2/aseqjoy.c:227:20: [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).
controllers[0]=atoi(optarg);
data/aseqjoy-0.0.2/aseqjoy.c:231:20: [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).
controllers[1]=atoi(optarg);
data/aseqjoy-0.0.2/aseqjoy.c:235:20: [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).

data/aseqjoy-0.0.2/aseqjoy.c:239:20: [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).

data/aseqjoy-0.0.2/aseqjoy.c:251:17: [2] (integer) atoi:
Unless checked, the resulting number can exceed the expected range

joystick_no=atoi(optarg);
data/aseqjoy-0.0.2/aseqjoy.c:146:7: [1] (buffer) read:
Check buffer boundaries if used in a loop including recursive loops
(CWE-120, CWE-20).
if (read(joy_fd, &js, sizeof(struct js_event)) != sizeof(struct js_event)) {
