+    cgrulesengd: remove umask(0)
+    
+    One of our partners has noticed that cgred daemon is creating a log file
+    (/var/log/cgred) with too wide permissions (0666) and that is seen as
+    a security bug because an untrusted user can write to otherwise
+    restricted area. CVE-2018-14348 has been assigned to this issue.
