+	  </p>
+	  <p>
+	    If your configuration uses the ${sort } expansion for items that can be controlled by an attacker (e.g. $local_part, $domain). The default config, as shipped by the Exim developers, does not contain ${sort }.
+	  </p>
+	  <p>
+	    The vulnerability is exploitable either remotely or locally and could
+be used to execute other programs with root privilege.  The ${sort }
