The SPA authentication driver was not abandoning authentication and moving + on to the next authenticator when an expansion was forced to fail, + contradicting the general specification for all authenticators. Instead it + was generating a temporary error. It now behaves as specified. + +50. The default ordering of permitted cipher suites for GnuTLS was pessimal + (the order specifies the preference for clients). The order is now AES256, + AES128, 3DES, ARCFOUR128. + +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. + +64. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs. + This has been fixed. + +65. Caching of lookup data for "hosts =" ACL conditions, when a named host list + was in use, was not putting the data itself into the right store pool; + consequently, it could be overwritten for a subsequent message in the same + SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked + the caching.) + +66. Added hosts_max_try_hardlimit to the smtp transport, default 50. + +67. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP + address", "IPv4 address", and "IPv6 address", respectively. Some calls of + the function were treating the return as a boolean value, which happened to + work because 0=false and not-0=true, but is not correct code. + +68. The host_aton() function was not handling scoped IPv6 addresses (those + with, for example, "%eth0" on the end) correctly. + +69. Fixed some compiler warnings in acl.c for the bitmaps specified with + negated items (that is, ~something) in unsigned ints. Some compilers + apparently mutter when there is no cast. + +70. If an address verification called from an ACL failed, and did not produce a + user-specific message (i.e. there was only a "system" message), nothing was + put in $acl_verify_message. In this situation, it now puts the system + message there. + Exim version 4.43 -----------------
