FINAL RESULTS:
data/libgxps-0.3.1/libgxps/gxps-archive.c:441:4: [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 (*buffer + *bytes_read, buf, bytes);
data/libgxps-0.3.1/libgxps/gxps-images.c:117:3: [2] (buffer) memcpy:

Make sure destination can always hold the source data.
memcpy (base, &p, sizeof (uint32_t));
data/libgxps-0.3.1/libgxps/gxps-images.c:136:3: [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 (base, &pixel, sizeof (uint32_t));
data/libgxps-0.3.1/libgxps/gxps-images.c:650:2: [2] (buffer) memcpy:

data/libgxps-0.3.1/test/test-gxps.c:79:9: [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.
char s[256];
data/libgxps-0.3.1/test/test-gxps.c:291:10: [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).

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).
