Change log file for Exim from version 4.21
-------------------------------------------
51. Small patch to Sieve code - explicitly set From: when generating an
autoreply.
+52. Exim crashed if a remote delivery caused a very long error message to be
+ recorded - for instance if somebody sent an entire SpamAssassin report back
+ as a large number of 550 error lines. This bug was coincidentally fixed by
+ increasing the size of one of Exim's internal buffers (big_buffer) that
+ happened as part of the Exiscan merge. However, to be on the safe side, I
+ have made the code more robust (and fixed the comments that describe what
+ is going on).
+
+53. Now that there can be additional text after "Completed" in log lines (if
+ the queue_time_overall log selector is set), a one-byte patch to exigrep
+ was needed to allow it to recognize "Completed" as not the last thing in
+ the line.
+
+54. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
+ patch that reportedly fixes this has been added. I am not expert enough to
+ create a test for it. This is what the patch creator wrote:
+
+ "I found a little strange behaviour of ldap code when working with
+ Windows 2003 AD Domain, where users was placed in more than one
+ Organization Units. When I tried to give exim partial DN, the exit code
+ of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
+ But simultaneously result of request was absolutely normal ldap result,
+ so I produce this patch..."
+
+55. Some experimental protocols are using DNS PTR records for new purposes. The
+ keys for these records are domain names, not reversed IP addresses. The
+ dnsdb PTR lookup now tests whether its key is an IP address. If not, it
+ leaves it alone. Component reversal etc. now happens only for IP addresses.
+
+56. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
+
+57. Double the size of the debug message buffer (to 2048) so that more of very
+ long debug lines gets shown.
+
+58. The exicyclog utility now does better if the number of log files to keep
+ exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
+
+59. Two changes related to the smtp_active_hostname option:
+
+ (1) $smtp_active_hostname is now available as a variable.
+ (2) The default for smtp_banner uses $smtp_active_hostname instead
+ of $primary_hostname.
+
+60. The host_aton() function is supposed to be passed a string that is known
+ to be a valid IP address. However, in the case of IPv6 addresses, it was
+ not checking this. This is a hostage to fortune. Exim now panics and dies
+ if the condition is not met. A case was found where this could be provoked
+ 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.
+
Exim version 4.43
