FINAL RESULTS:
data/vagalume-0.8.6/src/util.c:102:17: [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, F_OK);
data/vagalume-0.8.6/src/main.c:94:23: [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 ((opt = getopt(argc, argv, "d:s:h")) != -1) {
data/vagalume-0.8.6/src/util.c:210:27: [3] (buffer) g_get_home_dir:
This function is synonymous with 'getenv("HOME")';it returns untrustable
input if the environment can beset by an attacker. It can have any content
and length, and the same variable can be set more than once (CWE-807,
CWE-20). Check environment variables carefully before using them.
homedir = g_get_home_dir ();
data/vagalume-0.8.6/src/dlwin.c:45:17: [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 text[bufsize];
data/vagalume-0.8.6/src/dlwin.c:135:9: [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 text[textsize];
data/vagalume-0.8.6/src/http.c:114:9: [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(dstbuf->buffer + writefrom, src, datasize);
data/vagalume-0.8.6/src/http.c:246:21: [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).
f = fopen(filename, "wb");
data/vagalume-0.8.6/src/lastfm-ws.c:259:57: [2] (integer) atol:
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).
atol ((char *) err);
data/vagalume-0.8.6/src/md5/md5.c:52:18: [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.

data/vagalume-0.8.6/src/md5/md5.c:203:2: [2] (buffer) memcpy:

Make sure destination can always hold the source data.
memcpy(xbuf, data, 64);
data/vagalume-0.8.6/src/md5/md5.c:354:2: [2] (buffer) memcpy:

memcpy(pms->buf + offset, p, copy);
data/vagalume-0.8.6/src/md5/md5.c:368:2: [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(pms->buf, p, left);
data/vagalume-0.8.6/src/radio.c:55:9: [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.

data/vagalume-0.8.6/src/uimisc.c:497:17: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential

data/vagalume-0.8.6/src/userconfig.c:220:9: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential

data/vagalume-0.8.6/src/userconfig.c:224:35: [2] (misc) fopen:
Check when opening files - can an attacker redirect it (via symlinks),

around to create a race condition, control its ancestors, or change its
contents? (CWE-362).

data/vagalume-0.8.6/src/util.c:35:18: [2] (buffer) char:

functions that limit length, or ensure that the size is larger than the
maximum possible length.
unsigned char digest[digestlen];
data/vagalume-0.8.6/src/util.c:44:17: [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(hexdigest + 2*i, "%02x", digest[i]);
data/vagalume-0.8.6/src/util.c:226:16: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential

functions that limit length, or ensure that the size is larger than the
maximum possible length.
char strvalue[maxlen];
data/vagalume-0.8.6/src/util.c:502:27: [2] (integer) atol:
Unless checked, the resulting number can exceed the expected range

input had no minus sign (large numbers can roll over into negative number;
consider saving to an unsigned value if that is intended).

data/vagalume-0.8.6/src/vgl-main-window.c:258:9: [2] (buffer) char:
