+    from a dnsdb PTR lookup with an IPv6 address that had more than 8
+    components; fortuitously, this particular loophole had already been fixed
+    by change 4.50/55 above.
+
+    If there are any other similar loopholes, the new check in host_aton()
+    itself should stop them being exploited. The report I received stated that
+    data on the command line could provoke the exploit when Exim was running as
+    exim, but did not say which command line option was involved. All I could
+    find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
+    running as the user.
+
+61. There was a buffer overflow vulnerability in the SPA authentication code
+    (which came originally from the Samba project). I have added a test to the
+    spa_base64_to_bits() function which I hope fixes it.
+
+62. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
+    os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
+
+63. The daemon start-up calls getloadavg() while still root for those OS that
+    need the first call to be done as root, but it missed one case: when
+    deliver_queue_load_max is set with deliver_drop_privilege. This is
+    necessary for the benefit of the queue runner, because there is no re-exec
+    when deliver_drop_privilege is set.
+
+64. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
+    This has been fixed.
+
+65. Caching of lookup data for "hosts =" ACL conditions, when a named host list
+    was in use, was not putting the data itself into the right store pool;
+    consequently, it could be overwritten for a subsequent message in the same
+    SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
+    the caching.)
+
+66. Added hosts_max_try_hardlimit to the smtp transport, default 50.
