FINAL RESULTS:
data/sensors-applet-3.0.0+git6/lib/sensors-applet-plugin.c:42:21: [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.
if (access(path, R_OK) == 0) {
data/sensors-applet-3.0.0+git6/plugins/aticonfig/aticonfig-plugin.c:54:21: [4] (shell) popen:
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.

data/sensors-applet-3.0.0+git6/sensors-applet/sensors-applet-plugins.c:130:14: [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.

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

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).
