Change log file for Exim from version 4.21
-------------------------------------------
+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.
+
+
+Exim version 4.76
+-----------------
+
+PP/01 The new ldap_require_cert option would segfault if used. Fixed.
+
+PP/02 Harmonised TLS library version reporting; only show if debugging.
+ Layout now matches that introduced for other libraries in 4.74 PP/03.
+
+PP/03 New openssl_options items: no_sslv2 no_sslv3 no_ticket no_tlsv1
+
+PP/04 New "dns_use_edns0" global option.
+
+PP/05 Don't segfault on misconfiguration of ref:name exim-user as uid.
+ Bugzilla 1098.
+
+PP/06 Extra paranoia around buffer usage at the STARTTLS transition.
+ nb: Exim is not vulnerable to http://www.kb.cert.org/vuls/id/555316
+
+TK/01 Updated PolarSSL code to 0.14.2.
+ Bugzilla 1097. Patch from Andreas Metzler.
+
+PP/07 Catch divide-by-zero in ${eval:...}.
+ Fixes bugzilla 1102.
+
+PP/08 Condition negation of bool{}/bool_lax{} did not negate. Fixed.
+ Bugzilla 1104.
+
+TK/02 Bugzilla 1106: CVE-2011-1764 - DKIM log line was subject to a
+ format-string attack -- SECURITY: remote arbitrary code execution.
+
+TK/03 SECURITY - DKIM signature header parsing was double-expanded, second
+ time unintentionally subject to list matching rules, letting the header
+ 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.
+
+

+ With thanks to Steve Haslam, Johannes Berg & Serge Demonchaux
+ for maintaining out-of-tree patches for some time.
+
+PP/01 Bugzilla 139: Documentation and portability issues.
+ Avoid GNU Makefile-isms, let Exim continue to build on BSD.
+ Handle per-OS dynamic-module compilation flags.
+
+PP/02 Let /dev/null have normal permissions.
+ The 4.73 fixes were a little too stringent and complained about the
+ permissions on /dev/null. Exempt it from some checks.
+ 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
+ privilege escalation vulnerability whereby the Exim run-time user
+ can cause root to append content of the attacker's choosing to
+ arbitrary files.
+
+PP/05 Bugzilla 1041: merged DCC maintainer's fixes for return code.
+ (Wolfgang Breyha)
+
+PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.

+ the case, and it resulted in successful deliveries going unlogged.
+ Fixed. Reported by Andreas Metzler.
+
+
Exim version 4.73
+-----------------
PP/01 Date: & Message-Id: revert to normally being appended to a message,
only prepend for the Resent-* case. Fixes regression introduced in

+PP/02 Include check_rfc2047_length in configure.default because we're seeing
+ increasing numbers of administrators be bitten by this.
+
+JJ/01 Added DISABLE_DKIM and comment to src/EDITME
+
+PP/03 Bugzilla 994: added openssl_options main configuration option.
+
+PP/04 Bugzilla 995: provide better SSL diagnostics on failed reads.
+
+PP/05 Bugzilla 834: provide a permit_coredump option for pipe transports.
+
+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.
+
+PP/09 Implemented reverse_ip expansion operator.
+
+PP/10 Bugzilla 937: provide a "debug" ACL control.
+
+PP/11 Bugzilla 922: Documentation dusting, patch provided by John Horne.

+
+PP/14 Build without WITH_CONTENT_SCAN. Path from Andreas Metzler.
+
+PP/15 Bugzilla 816: support multiple condition rules on Routers.
+
+PP/16 Add bool_lax{} expansion operator and use that for combining multiple
+ condition rules, instead of bool{}. Make both bool{} and bool_lax{}
+ ignore trailing whitespace.
+
+JJ/02 prevent non-panic DKIM error from being sent to paniclog
+
+JJ/03 added tcp_wrappers_daemon_name to allow host entries other than
+ "exim" to be used
+
+PP/17 Fix malware regression for cmdline scanner introduced in PP/08.
+ Notification from Dr Andrew Aitchison.
+
+PP/18 Change ClamAV response parsing to be more robust and to handle ClamAV's
+ ExtendedDetectionInfo response format.
+ Notification from John Horne.
+
+PP/19 OpenSSL 1.0.0a compatibility const-ness change, should be backwards
+ compatible.
+
+PP/20 Added a CONTRIBUTING file. Fixed the documentation build to use http:
+ XSL and documented dependency on system catalogs, with examples of how
+ 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
+ they are going to be used with root privileges, not just the default
+ configuration file.
+
+DW/24 Bugzilla 1044: CVE-2010-4345 - part three: remove ALT_CONFIG_ROOT_ONLY
+ option (effectively making it always true).
+
+DW/25 Add TRUSTED_CONFIG_PREFIX_FILE option to allow alternative configuration
+ 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.
+
+NM/01 Fixed bug #1002 - Message loss when using multiple deliveries
+
+
