FINAL RESULTS:
data/guifications-2.16/src/gf_file.c:104:9: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.
return access(filename, mode);
data/guifications-2.16/src/gf_preferences.c:606:2: [4] (shell) system:
This causes a new program to execute and is difficult to use safely
(CWE-78). try using a library call that implements the same functionality
if available.
system(command);
data/guifications-2.16/src/gf_notification.c:467:3: [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(t);
data/guifications-2.16/src/gf_theme_editor.c:457:31: [3] (random) g_random_int:
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.
dir = g_strdup_printf(".%x", g_random_int());
data/guifications-2.16/src/guifications.c:72:2: [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(t);
data/guifications-2.16/src/gf_internal.h:58:18: [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).
# define g_fopen fopen
data/guifications-2.16/src/gf_internal.h:66:17: [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).
# define g_open open
data/guifications-2.16/src/gf_item_offset.c:83:18: [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).
offset->value = atoi(data);
data/guifications-2.16/src/gf_item_text.c:245:22: [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).
item_text->width = atoi(data);
data/guifications-2.16/src/gf_item_text.c:419:9: [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.
static char buff[80];
data/guifications-2.16/src/gf_notification.c:96:27: [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).
notification->use_gtk = atoi(data);
data/guifications-2.16/src/gf_notification.c:104:25: [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).
notification->width = atoi(data);
data/guifications-2.16/src/gf_notification.c:108:26: [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).
notification->height = atoi(data);
data/guifications-2.16/src/gf_theme.c:101:16: [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).
api_version = atoi(xmlnode_get_attrib(parent, "api"));
data/guifications-2.16/src/gf_event.c:502:28: [1] (buffer) strlen:

perform an over-read (it could cause a crash if unprotected) (CWE-126).

data/guifications-2.16/src/gf_file.c:41:15: [1] (buffer) fgetc:

(CWE-120, CWE-20).
