FINAL RESULTS:
data/ganv-1.6.0/src/ganv_bench.cpp:137:2: [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(time(NULL));
data/ganv-1.6.0/src/Canvas.cpp:767:14: [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).
FILE* tmp = fopen("/dev/null", "w");

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).
FILE* fd = fopen(filename.c_str(), "w");
data/ganv-1.6.0/src/ganv_bench.cpp:38:2: [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[8];

char name[8];
data/ganv-1.6.0/src/ganv_bench.cpp:126:23: [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).
const int canvas_w = atoi(argv[arg++]);
data/ganv-1.6.0/src/ganv_bench.cpp:127:23: [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).
const int canvas_h = atoi(argv[arg++]);
data/ganv-1.6.0/src/ganv_bench.cpp:133:24: [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).
const int n_modules = atoi(argv[arg++]);
data/ganv-1.6.0/src/ganv_bench.cpp:134:24: [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).
const int n_circles = atoi(argv[arg++]);
data/ganv-1.6.0/src/ganv_bench.cpp:135:24: [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).
const int n_edges = atoi(argv[arg++]);
data/ganv-1.6.0/src/module.c:852:2: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
memcpy(copy, impl->ports->pdata, sizeof(GanvPort*) * len);
