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.) + Exim version 4.43 -----------------
