+Subject: [PATCH] Ensure the ssl-use-system-ca-file property is set to true on
+ all SoupSessions.
+
+The default SoupSessionSync and SoupSessionAsync behaviour does not perform any
+TLS certificate validation, unless the ssl-use-system-ca-file property is set
+to true.
+
+This mitigates CVE-2016-20011.
