+Subject: [PATCH 2/3] wpa_cli: Use os_exec() for action script execution
+
+Use os_exec() to run the action script operations to avoid undesired
+command line processing for control interface event strings. Previously,
+it could have been possible for some of the event strings to include
+unsanitized data which is not suitable for system() use. (CVE-2014-3686)
