+JH/40 Fix a memory-handling bug: when a connection carried multiple messages
+      and an ACL use a lookup for checking either the local_part or domain,
+      stale data could be accessed.  Ensure that variable references are

+JH/41 Bug 2571: Fix SPA authenticator.  Running as a server, an offset supplied
+      by the client was not checked as pointing within response data before
+      being used.  A malicious client could thus cause an out-of-bounds read and
+      possibly gain authentication.  Fix by adding the check.
