FINAL RESULTS:
data/hwloc-2.4.0~rc1+dfsg/hwloc/topology-linux.c:503:10: [5] (race) readlink:
This accepts filename arguments; if an attacker can move those files or
change the link content, a race condition results. Also, it does not
terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
return readlink(p, l, ll);
data/hwloc-2.4.0~rc1+dfsg/hwloc/components.c:230:3: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf(componentsymbolname, "%s_component", basename);
data/hwloc-2.4.0~rc1+dfsg/hwloc/dolib.c:41:7: [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.
if (system(s)) {
data/hwloc-2.4.0~rc1+dfsg/hwloc/misc.c:47:9: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
ret = vsnprintf(str, size, format, ap);
data/hwloc-2.4.0~rc1+dfsg/hwloc/misc.c:67:11: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
ret = vsnprintf(fakestr, fakesize, format, ap);
data/hwloc-2.4.0~rc1+dfsg/hwloc/topology-linux.c:471:12: [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(p, m);
data/hwloc-2.4.0~rc1+dfsg/hwloc/topology-linux.c:2520:3: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.

data/hwloc-2.4.0~rc1+dfsg/hwloc/topology-linux.c:2542:3: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.

data/hwloc-2.4.0~rc1+dfsg/hwloc/topology-linux.c:2578:5: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf(distancepath, "%s/node%u/distance", path, osnode);
data/hwloc-2.4.0~rc1+dfsg/hwloc/topology-linux.c:2616:3: [4] (buffer) strcpy:
Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused).
strcpy(path+pathlen, dmi_name);
data/hwloc-2.4.0~rc1+dfsg/hwloc/topology-linux.c:3482:3: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.

data/hwloc-2.4.0~rc1+dfsg/hwloc/topology-linux.c:3485:5: [4] (buffer) sprintf:
