FINAL RESULTS:
data/miniasm-0.3+dfsg/dotter.c:68:14: [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.
while ((c = getopt(argc, argv, "m:i:s:w:f:Ld")) >= 0) {
data/miniasm-0.3+dfsg/main.c:44:14: [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.

data/miniasm-0.3+dfsg/asm.c:80:2: [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[32];
data/miniasm-0.3+dfsg/asm.c:83:3: [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(name, "utg%.6d%c", i + 1, "lc"[p->circ]);
data/miniasm-0.3+dfsg/dotter.c:69:29: [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/miniasm-0.3+dfsg/dotter.c:71:33: [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/miniasm-0.3+dfsg/dotter.c:72:30: [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/miniasm-0.3+dfsg/dotter.c:73:34: [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

consider saving to an unsigned value if that is intended).
else if (c == 'f') font_size = atoi(optarg);
data/miniasm-0.3+dfsg/eps.h:8:21: [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 eps_open(s) fopen((s),"w+")
data/miniasm-0.3+dfsg/kseq.h:135:4: [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(str->s + str->l, ks->buf + ks->begin, i - ks->begin); \
data/miniasm-0.3+dfsg/kvec.h:74:3: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
