+Exim version 4.78

+PP/01 Handle short writes when writing local log-files.
+ In practice, only affects FreeBSD (8 onwards).
+ Bugzilla 1053, with thanks to Dmitry Isaikin.
+
+NM/01 Bugzilla 949 - Documentation tweak
+
+
+Exim version 4.77
+-----------------
+
+PP/01 Solaris build fix for Oracle's LDAP libraries.
+ Bugzilla 1109, patch from Stephen Usher.
+
+TF/01 HP/UX build fix: avoid arithmetic on a void pointer.
+
+TK/01 DKIM Verification: Fix relaxed canon for empty headers w/o
+ whitespace trailer
+
+TF/02 Fix a couple more cases where we did not log the error message
+ when unlink() failed. See also change 4.74-TF/03.
+
+TF/03 Make the exiwhat support code safe for signals. Previously Exim might
+ lock up or crash if it happened to be inside a call to libc when it
+ got a SIGUSR1 from exiwhat.
+
+ The SIGUSR1 handler appends the current process status to the process
+ log which is later printed by exiwhat. It used to use the general
+ purpose logging code to do this, but several functions it calls are
+ not safe for signals.
+
+ The new output code in the SIGUSR1 handler is specific to the process
+ log, and simple enough that it's easy to inspect for signal safety.
+ Removing some special cases also simplifies the general logging code.
+ Removing the spurious timestamps from the process log simplifies
+ exiwhat.
+
+TF/04 Improved ratelimit ACL condition.
+
+ The /noupdate option has been deprecated in favour of /readonly which
+ has clearer semantics. The /leaky, /strict, and /readonly update modes
+ are mutually exclusive. The update mode is no longer included in the
+ database key; it just determines when the database is updated. (This
+ means that when you upgrde Exim will forget old rate measurements.)
+
+ Exim now checks that the per_* options are used with an update mode that
+ makes sense for the current ACL. For example, when Exim is processing a
+ message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
+ per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
+ must specify per_mail/readonly. If you omit the update mode it defaults to
+ /leaky where that makes sense (as before) or /readonly where required.
+
+ The /noupdate option is now undocumented but still supported for
+ backwards compatibility. It is equivalent to /readonly except that in
+ ACLs where /readonly is required you may specify /leaky/noupdate or
+ /strict/noupdate which are treated the same as /readonly.
+
+ A useful new feature is the /count= option. This is a generalization
+ of the per_byte option, so that you can measure the throughput of other
+ aggregate values. For example, the per_byte option is now equivalent
+ to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
+
+ The per_rcpt option has been generalized using the /count= mechanism
+ (though it's more complicated than the per_byte equivalence). When it is
+ used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
+ measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
+ or in a non-SMTP ACL it adds all the recipients in one go. (The latter
+ /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
+ Note that using per_rcpt with a non-readonly update mode in more than
+ one ACL will cause the recipients to be double-counted. (The per_mail
+ and per_byte options don't have this problem.)
+
+ The handling of very low rates has changed slightly. If the computed rate
+ is less than the event's count (usually one) then this event is the first
+ after a long gap. In this case the rate is set to the same as this event's
+ count, so that the first message of a spam run is counted properly.
+
+ The major new feature is a mechanism for counting the rate of unique
+ events. The new per_addr option counts the number of different
+ recipients that someone has sent messages to in the last time period. It
+ behaves like per_rcpt if all the recipient addresses are different, but
+ duplicate recipient addresses do not increase the measured rate. Like
+ the /count= option this is a general mechanism, so the per_addr option
+ is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
+ example, measure the rate that a client uses different sender addresses
+ with the options per_mail/unique=$sender_address. There are further
+ details in the main documentation.
+

+ format-string attack -- SECURITY: remote arbitrary code execution.
+
+TK/03 SECURITY - DKIM signature header parsing was double-expanded, second

+ cause arbitrary Exim lookups (of items which can occur in lists, *not*
+ arbitrary string expansion). This allowed for information disclosure.
+
+PP/09 Fix another SIGFPE (x86) in ${eval:...} expansion, this time related to
+ INT_MIN/-1 -- value coerced to INT_MAX.

+ Reported by Andreas M. Kirchwitz.
+
+PP/03 Report version information for many libraries, including
+ Exim version information for dynamically loaded libraries. Created
+ version.h, now support a version extension string for distributors
+ who patch heavily. Dynamic module ABI change.
+
+PP/04 CVE-2011-0017 - check return value of setuid/setgid. This is a

+ (Wolfgang Breyha)
+
+PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.

+ Fixed. Reported by Andreas Metzler.
+
+

+
+PP/06 Adjust NTLM authentication to handle SASL Initial Response.
+
+PP/07 If TLS negotiated an anonymous cipher, we could end up with SSL but
+ without a peer certificate, leading to a segfault because of an
+ assumption that peers always have certificates. Be a little more
+ paranoid. Problem reported by Martin Tscholak.
+
+PP/08 Bugzilla 926: switch ClamAV to use the new zINSTREAM API for content
+ filtering; old API available if built with WITH_OLD_CLAMAV_STREAM=yes
+ NB: ClamAV planning to remove STREAM in "middle of 2010".
+ CL also introduces -bmalware, various -d+acl logging additions and
+ more caution in buffer sizes.

+ it normally works.
+
+DW/21 Added Valgrind hooks in store.c to help it capture out-of-bounds store
+ access.
+
+DW/22 Bugzilla 1044: CVE-2010-4345 - partial fix: restrict default behaviour
+ of CONFIGURE_OWNER and CONFIGURE_GROUP options to no longer allow a
+ configuration file which is writeable by the Exim user or group.
+
+DW/23 Bugzilla 1044: CVE-2010-4345 - part two: extend checks for writeability
+ of configuration files to cover files specified with the -C option if

+ files to be used while preserving root privileges.
+
+DW/26 Set FD_CLOEXEC on SMTP sockets after forking in the daemon, to ensure
+ that rogue child processes cannot use them.
+
+PP/27 Bugzilla 1047: change the default for system_filter_user to be the Exim
+ run-time user, instead of root.
+
+PP/28 Add WHITELIST_D_MACROS option to let some macros be overridden by the
+ Exim run-time user without dropping privileges.
+
+DW/29 Remove use of va_copy() which breaks pre-C99 systems. Duplicate the
+ result string, instead of calling string_vformat() twice with the same
+ arguments.
+
+DW/30 Allow TRUSTED_CONFIG_PREFIX_FILE only for Exim or CONFIGURE_OWNER, not
+ for other users. Others should always drop root privileges if they use
+ -C on the command line, even for a whitelisted configure file.
+
+DW/31 Turn TRUSTED_CONFIG_PREFIX_FILE into TRUSTED_CONFIG_FILE. No prefixes.
