JH/12 Bug 3112: Fix logging of config-file position for "obsolete lookup
syntax". Previously, the end of the top-level file was reported.
+JH/13 Bug 3120: Fix parsing of DKIM pubkey DNS record. Previously a crafted
+ record could crash the meesage recieve process. Investigation by
+ Maxim Galaganov.
+
+JH/14 Bug 3116: Fix crash in dkim signing. On kernels supporting immutable
+ memory segments, a write was done into one when a constant string was
+ configured for a transport's dkim private key.
+
+JH/15 Disallow tainted metadata in lists.
+ - Change-of-separator prefixes are handled specially when they are
+ explicit text; only the remainder of the list is expanded. A change-of-
+ separator resulting from expansion will not take effect if tainted.
+ - Elements starting with a plus-sign (named-list inclusion,
+ case-interpretation etc) and (hostlist) @[] (et al) are not handled
+ specially and are still operative at this time - but warnings are logged;
+ if any of these are needed in a list with a tainted element (which taints
+ the entire list at string-expansion time) then a named-list can be used
+ for that element.
+ - Exclamation-marks ("!" signifying negation) are not checked for taint
+ at this time.
+
+JH/16 Bug 3124: Fix theoretical crash in received connection, triggerable by a
+ crafted packet with massive count of IP options. A buffer overflow was
+ detected, but a null-deref results. In practice, IP packets with options
+ are rare (to non-existent). Exim refuses connections having any, but this
+ issue was in the coding for logging preceding that refusal. If coredumps
+ were enabled (not common), an attack could cause filesystem space usage.
+
+JH/17 Bug 3126: Fix build error in the ibase lookup. Find & fix by
+ Andrew Aitchison.
