FINAL RESULTS:
data/lm-sensors-3.6.0/lib/sysfs.c:720:13: [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.
sub_len = readlink(linkpath, subsys_path, NAME_MAX - 1);
data/lm-sensors-3.6.0/lib/sysfs.c:724:14: [5] (race) readlink:

terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
sub_len = readlink(linkpath, subsys_path, NAME_MAX - 1);
data/lm-sensors-3.6.0/lib/sysfs.c:360:16: [4] (buffer) sscanf:
The scanf() family's %s operation, without a limit specification, permits
buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
different input function. If the scanf format is influenceable by an
attacker, it's exploitable.
if ((count = sscanf(name, matches[i].name, nr, &c)))
data/lm-sensors-3.6.0/prog/sensord/chips.c:105:2: [4] (buffer) sprintf:

sprintf(rrdBuff + strlen(rrdBuff), ":%s",
data/lm-sensors-3.6.0/prog/sensord/sensord.c:53:2: [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.
vsnprintf(buffer, LOG_BUFFER, fmt, ap);
data/lm-sensors-3.6.0/prog/sensors/chips.c:232:3: [4] (format) printf:

printf(fmt, limits[i].name, limits[i].value,
data/lm-sensors-3.6.0/prog/sensors/main.c:147:2: [4] (buffer) strcpy:

easily misused).
