FINAL RESULTS:
data/libhugetlbfs-2.23/elflink.c:356:8: [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.
ret = readlink("/proc/self/exe", binary, PATH_MAX);
data/libhugetlbfs-2.23/hugeadm.c:454:7: [5] (race) chown:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchown( ) instead.
if (chown(path, uid, gid)) {
data/libhugetlbfs-2.23/hugeadm.c:460:7: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
if (chmod(path, mode)) {
data/libhugetlbfs-2.23/hugeadm.c:559:22: [5] (race) readlink:

terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.

data/libhugetlbfs-2.23/hugeutils.c:1040:2: [5] (buffer) strncat:
Easily used incorrectly (e.g., incorrectly computing the correct maximum
size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
or automatically resizing strings. Risk is high; the length parameter
appears to be a constant, instead of computing the number of characters
left.
strncat(name, "/libhugetlbfs.tmp.XXXXXX", sizeof(name)-1);
data/libhugetlbfs-2.23/elflink.c:201:8: [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.
len = vsnprintf(dst, PATH_MAX+1, fmt, ap);

data/libhugetlbfs-2.23/hugeadm.c:345:3: [4] (format) printf:

snprintf (warning: strncat is easily misused).
strcat(options, limits);
data/libhugetlbfs-2.23/hugeadm.c:1026:8: [4] (shell) system:

if available.
ret = system(mkswap_cmd);
data/libhugetlbfs-2.23/hugeadm.c:1099:7: [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.

snprintf (warning: strncat is easily misused).

easily misused).
strcpy(filename, MEMINFO);

different input function.
