From 2c6ea642663e2a44efc8583fae7c54b7b98f72b3 Mon Sep 17 00:00:00 2001
From: Ariadne Conill <ariadne@dereferenced.org>

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.
