+        A security vulnerability exists in all versions of
+        <application>xdg-utils</application> from version 1.1.0rc1 when handling
+        mailto: URIs. An attacker could potentially send a victim a URI that
+        automatically attaches a sensitive file to a new email. If a victim user
+        does not notice that an attachment was added and sends the email, this
+        could result in sensitive information disclosure.
+      </para>
+
+      <para>
+        To mitigate this flaw, either do not use mailto links at all, or always
+        double-check in the user interface that there are no unwanted attachments
+        before sending emails, especially when the email originates from clicking
+        on a mailto link.
