+MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
+      conversion specification without a maximum field width, thereby enabling
+      a rogue spamd server to cause a buffer overflow. While nobody in their
+      right mind would setup Exim to query an untrusted spamd server, an
+      attacker that gains access to a server running spamd could potentially
+      exploit this vulnerability to run arbitrary code as the Exim user.
