8.12.8/8.12.8 2003/02/11
SECURITY: Fix a remote buffer overflow in header parsing by
dropping sender and recipient header comments if the
comments are too long. Problem noted by Mark Dowd
of ISS X-Force.
Fix a potential non-exploitable buffer overflow in parsing the
.cf queue settings and potential buffer underflow in
parsing ident responses. Problem noted by Yichen Xie of
Stanford University Compilation Group.
Fix ETRN #queuegroup command: actually start a queue run for
the selected queue group. Problem noted by Jos Vos.
If MaxMimeHeaderLength is set and a malformed MIME header is fixed,
log the fixup as "Fixed MIME header" instead of "Truncated
MIME header". Problem noted by Ian J Hart.
CONFIG: Fix regression bug in proto.m4 that caused a bogus
error message: "FEATURE() should be before MAILER()".
MAIL.LOCAL: Be more explicit in some error cases, i.e., whether
a mailbox has more than one link or whether it is not
a regular file. Patch from John Beck of Sun Microsystems.
8.12.7/8.12.7 2002/12/29
Properly clean up macros to avoid persistence of session data
across various connections. This could cause session
oriented restrictions, e.g., STARTTLS requirements,
to erroneously allow a connection. Problem noted
by Tim Maletic of Priority Health.
Do not lookup MX records when sorting the MSP queue. The MSP
only needs to relay all mail to the MTA. Problem found
by Gary Mills of the University of Manitoba.
Do not restrict the length of connection information to 100
characters in some logging statements. Problem noted by
Erik Parker.
When converting an enhanced status code to an exit status, use
EX_CONFIG if the first digit is not 2, 4, or 5 or if *.1.5
is used.
Reset macro $x when receiving another MAIL command. Problem
noted by Vlado Potisk of Wigro s.r.o.
Don't bother setting the permissions on the build area statistics
file, the proper permissions will be put on the file at
install time. This fixes installation over NFS for some
users. Problem noted by Martin J. Dellwo of 3-Dimensional
Pharmaceuticals, Inc.
Fix problem of decoding SASLv2 encrypted data. Problem noted by
Alex Deiter of Mobile TeleSystems, Komi Republic.
Log milter socket open errors at MilterLogLevel 1 or higher instead
of 11 or higher.
Print early system errors to the console instead of silently
exiting. Problem noted by James Jong of IBM.
Do not process a queue group if Runners is set to 0, regardless
of whether F=f or sendmail is run in verbose mode (-v).
The use of -qGname will still force queue group "name"
to be run even if Runners=0.
Change the level for logging the fact that a daemon is refusing
connections due to high load from LOG_INFO to LOG_NOTICE.
Patch from John Beck of Sun Microsystems.
Use location information for submit.cf from NetInfo
(/locations/sendmail/submit.cf) if available.
Re-enable ForkEachJob which was lost in 8.12.0. Problem noted by
Neil Rickert of Northern Illinois University.
Make behavior of /canon in debug mode consistent with usage in
rulesets. Patch from Shigeno Kazutaka of IIJ.
Fix a potential memory leak in envelope splitting. Problem noted
by John Majikes of IBM.
Do not try to share an mailbox database LDAP connection across
different processes. Problem noted by Randy Kunkee.
Fix logging for undelivered recipients when the SMTP connection
times out during message collection. Problem noted by Neil
Rickert of Northern Illinois University.
Avoid problems with QueueSortOrder=random due to problems with
qsort() on Solaris (and maybe some other operating systems).
Problem noted by Stephan Schulz of Gruner+Jahr..
If -f "" is specified, set the sender address to "<>". Problem
noted by Matthias Andree.
Fix formatting problem of footnotes for plain text output on some
versions of tmac. Patch from Per Hedeland.
Portability:
Berkeley DB 4.1 support (requires at least 4.1.25).
Some getopt(3) implementations in GNU/Linux are broken
and pass a NULL pointer to an option which requires
an argument, hence the builtin version of
sendmail is used instead. This can be overridden
by using -DSM_CONF_GETOPT=0. Problem noted by
Vlado Potisk of Wigro s.r.o.
Support for nph-1.2.0 from Mark D. Roth of the University
of Illinois at Urbana-Champaign.
Support for FreeBSD 5.0's MAC labeling from Robert Watson
of the TrustedBSD Project.
Support for reading the number of processors on an IRIX
system from Michel Bourget of SGI.

Interix support from Nedelcho Stanev of Atlantic Sky
Corporation.
Update Mac OS X/Darwin portability from Wilfredo Sanchez.
CONFIG: Enforce tls_client restrictions even if delay_checks
is used. Problem noted by Malte Starostik.
CONFIG: Deal with an empty hostname created via bogus
DNS entries to get around access restrictions.
Problem noted by Kai Schlichting.
CONFIG: Use FEATURE(`msp', `[127.0.0.1]') in submit.mc by default
to avoid problems with hostname resolution for localhost
which on many systems does not resolve to 127.0.0.1 (or
::1 for IPv6). If you do not use IPv4 but only IPv6 then
you need to change submit.mc accordingly, see the comment
in the file itself.
CONFIG: Set confDONT_INIT_GROUPS to True in submit.mc to avoid
error messages from initgroups(3) on AIX 4.3 when sending
mail to non-existing users. Problem noted by Mark Roth of
the University of Illinois at Urbana-Champaign.
CONFIG: Allow local_procmail to override local_lmtp settings.
CONFIG: Always allow connections from 127.0.0.1 or IPv6:::1 to
relay.
CONTRIB: cidrexpand: Deal with the prefix tags that may be included
in access_db.
CONTRIB: New version of doublebounce.pl contributed by Leo Bicknell.
LIBMILTER: On Solaris libmilter may get into an endless loop if
an error in the communication from/to the MTA occurs.
Patch from Gurusamy Sarathy of Active State.
LIBMILTER: Ignore EINTR from sigwait(3) which may happen on Tru64.
Patch from from Jose Marcio Martins da Cruz of Ecole
Nationale Superieure des Mines de Paris.
MAIL.LOCAL: Fix a truncation race condition if the close() on
the mailbox fails. Problem noted by Tomoko Fukuzawa of
Sun Microsystems.
MAIL.LOCAL: Fix a potential file descriptor leak if mkstemp(3)
fails. Patch from John Beck of Sun Microsystems.
SMRSH: SECURITY: Only allow regular files or symbolic links to be
used for a command. Problem noted by David Endler of
iDEFENSE, Inc.
New Files:

Large number of bug fixes and feature enhancements, especially Milter
(Mail Filter) support and by default installation of sendmail does not use
set-user-ID root anymore.
confDELIVERBYMIN and confSHAREDMEMORYKEY have been renamed to
confDELIVER_BY_MIN and confSHARED_MEMORY_KEY, respectively.
The macro {sendmailMTACluster} replaces {LDAPCluster}.
Added FEATURE(`queuegroup') for selecting a queue group in the
access database.
Added OSTYPE(`freebsd4')
sendmail/TUNING gives some hints about performance tuning.
Any IPv6 addresses used in configuration should be prefixed by the
"IPv6:" tag to identify the address properly. For example, if you
want to add the IPv6 address [2002:c0a8:51d2::23f4] to class {w},
you would need to add [IPv6:2002:c0a8:51d2::23f4]; if you want to
use it in the access database, you would need to use
IPv6:2002:c0a8:51d2::23f4 on the left hand side.
8.11.3/8.11.3 2001/02/27
Prevent a segmentation fault when a bogus value was used in the
LDAPDefaultSpec option's -r, -s, or -M flags and if a bogus
option was used. Problem noted by Allan E Johannesen of
Worcester Polytechnic Institute.
Prevent "token too long" message by shortening {currHeader} which
could be too long if the last copied character was a quote.
Problem detected by Jan Krueger of digitalanswers
communications consulting gmbh.
Additional IPv6 check for unspecified addresses. Patch from
Jun-ichiro itojun Hagino of the KAME Project.
Do not ignore the ClientPortOptions setting if DaemonPortOptions
Modifier=b (bind to same interface) is set and the
connection came in from the command line.
Do not bind to the loopback address if DaemonPortOptions
Modifier=b (bind to same interface) is set. Patch from
John Beck of Sun Microsystems.
Properly deal with open failures on non-optional maps used in
check_* rulesets by returning a temporary failure.
Buffered file I/O files were not being properly fsync'ed to disk
when they were committed.
Properly encode '=' for the AUTH= parameter of the MAIL command.
Problem noted by Hadmut Danisch.
Under certain circumstances the macro {server_name} could be set
to the wrong hostname (of a previous connection), which may
cause some rulesets to return wrong results. This would
usually cause mail to be queued up and delivered later on.
Ignore F=z (LMTP) mailer flag if $u is given in the mailer A=
equate. Problem noted by Motonori Nakamura of Kyoto
University.
Work around broken accept() implementations which only partially
fill in the peer address if the socket is closed before
accept() completes.
Return an SMTP "421" temporary failure if the data file can't be
opened where the "354" reply would normally be given.
Prevent a CPU loop in trying to expand a macro which doesn't exist
in a queue run. Problem noted by Gordon Lack of Glaxo
Wellcome.
If delivering via a program and that program exits with EX_TEMPFAIL,
note that fact for the mailq display instead of just showing
"Deferred". Problem noted by Motonori Nakamura of Kyoto
University.
If doing canonification via /etc/hosts, try both the fully
qualified hostname as well as the first portion of the
hostname. Problem noted by David Bremner of the
University of New Brunswick.
Portability:
Fix a compilation problem for mail.local and rmail if SFIO
is in use. Problem noted by Auteria Wally
Winzer Jr. of Champion Nutrition.
IPv6 changes for platforms using KAME. Patch from
Jun-ichiro itojun Hagino of the KAME Project.
OpenBSD 2.7 and higher has srandomdev(3). OpenBSD 2.8 and
higher has BSDI-style login classes. Patch from
Todd C. Miller of Courtesan Consulting.
Unixware 7.1.1 doesn't allow h_errno to be set directly if
sendmail is being compiled with -kthread. Problem
noted by Orion Poplawski of CQG, Inc.
CONTRIB: buildvirtuser: Substitute current domain for $DOMAIN and
current left hand side for $LHS in virtuser files.
DEVTOOLS: Do not pass make targets to recursive Build invocations.
Problem noted by Jeff Bronson of J.D. Bronson, Inc.
MAIL.LOCAL: In LMTP mode, do not return errors regarding problems
storing the temporary message file until after the remote
side has sent the final DATA termination dot. Problem
noted by Allan E Johannesen of Worcester Polytechnic
Institute.
MAIL.LOCAL: If LMTP mode is set, give a temporary error if users
are also specified on the command line. Patch from
Motonori Nakamura of Kyoto University.
PRALIASES: Skip over AliasFile specifications which aren't based on
database files (i.e., only show dbm, hash, and btree).
Renamed Files:
devtools/OS/OSF1.V5.0 => devtools/OS/OSF1.V5.x
8.11.2/8.11.2 2000/12/29
Prevent a segmentation fault when trying to set a class in
address test mode due to a negative array index. Audit
other array indexing. This bug is not believed to be
exploitable. Noted by Michal Zalewski of the "Internet for
Schools" project (IdS).
Add an FFR (for future release) to drop privileges when using
address test mode. This will be turned on in 8.12. It can
be enabled by compiling with:
APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS')
in your devtools/Site/site.config.m4 file. Suggested by
Michal Zalewski of the "Internet for Schools" project (IdS).
Fix potential problem with Cyrus-SASL security layer which may have
caused I/O errors, especially for mechanism DIGEST-MD5.
When QueueSortOrder was set to host, sendmail might not read
enough of the queue file to determine the host, making the
sort sub-optimal. Problem noted by Jeff Earickson of
Colby College.
Don't issue DSNs for addresses which use the NOTIFY parameter (per
RFC 1891) but don't have FAILURE as value.
Initialize Cyrus-SASL library before the SMTP daemon is started.
This implies that every change to SASL related files requires
a restart of the daemon, e.g., Sendmail.conf, new SASL
mechanisms (in form of shared libraries).
Properly set the STARTTLS related macros during a queue run for
a cached connection. Bug reported by Michael Kellen of
NxNetworks, Inc.
Log the server name in relay= for ruleset tls_server instead of the
client name.
Include original length of bad field/header when reporting
MaxMimeHeaderLength problems. Requested by Ulrich Windl of
the Universitat Regensburg.
Fix delivery to set-user-ID files that are expanded from aliases in
DeliveryMode queue. Problem noted by Ric Anderson of the
University of Arizona.
Fix LDAP map -m (match only) flag. Problem noted by Jeff Giuliano
of Collective Technologies.
Avoid using a negative argument for sleep() calls when delaying answers
to EXPN/VRFY commands on systems which respond very slowly.
Problem noted by Mikolaj J. Habryn of Optus Internet
Engineering.

definition. Problem noted by Kari Hurtta of the Finnish
Meteorological Institute.
Fix IPv6 check for unspecified addresses. Patch from
Jun-ichiro itojun Hagino of the KAME Project.
Fix return values for IRIX nsd map. From Kari Hurtta of the Finnish
Meteorological Institute.
Fix parsing of DaemonPortOptions and ClientPortOptions. Read all
of the parameters to find Family= setting before trying to
interpret Addr= and Port=. Problem noted by Valdis
Kletnieks of Virginia Tech.
When delivering to a file directly from an alias, do not call
initgroups(); instead use the DefaultUser group information.
Problem noted by Marc Schaefer of ALPHANET NF.
RunAsUser now overrides the ownership of the control socket, if
created. Otherwise, sendmail can not remove it upon
close. Problem noted by Werner Wiethege.
Fix ConnectionRateThrottle counting as the option is the number of
overall connections, not the number of connections per
socket. A future version may change this to per socket
counting.
Portability:
Clean up libsmdb so it functions properly on platforms
where sizeof(u_int32_t) != sizeof(size_t). Problem
noted by Rein Tollevik of Basefarm AS.
Fix man page formatting for compatibility with Solaris'
whatis. From Stephen Gildea of InTouch Systems, Inc.
UnixWare 7 includes snprintf() support. From Larry
Rosenman.
IPv6 changes for platforms using KAME. Patch from
Jun-ichiro itojun Hagino of the KAME Project.
Avoid a typedef compile conflict with Berkeley DB 3.X and
Solaris 2.5 or earlier. Problem noted by Bob Hughes

Add preliminary support for AIX 5. Contributed by
Valdis Kletnieks of Virginia Tech.
Solaris 9 load average support from Andrew Tucker of Sun
Microsystems.
CONFIG: Reject addresses of the form a!b if FEATURE(`nouucp', `r')
is used. Problem noted by Phil Homewood of Asia Online,
patch from Neil Rickert of Northern Illinois University.
CONFIG: Change the default DNS based blacklist server for
FEATURE(`dnsbl') to blackholes.mail-abuse.org.
CONFIG: Deal correctly with the 'C' flag in {daemon_flags}, i.e.,

patch by Motonori Nakamura of Kyoto University.
CONFIG: New OSTYPE(`aix5') contributed by Valdis Kletnieks of
Virginia Tech.
CONFIG: Pass the illegal header form <list:;> through untouched
instead of making it worse. Problem noted by Motonori
Nakamura of Kyoto University.
CONTRIB: Added buildvirtuser (see `perldoc contrib/buildvirtuser`).
CONTRIB: qtool.pl: An empty queue is not an error. Problem noted
by Jan Krueger of digitalanswers communications consulting
gmbh.
CONTRIB: domainmap.m4: Handle domains with '-' in them. From Mark
Roth of the University of Illinois at Urbana-Champaign.
DEVTOOLS: Change the internal devtools OS, REL, and ARCH m4
variables into bldOS, bldREL, and bldARCH to prevent
namespace collisions. Problem noted by Motonori Nakamura
of Kyoto University.
RMAIL: Undo the 8.11.1 change to use -G when calling sendmail. It
causes some changes in behavior and may break rmail for
installations where sendmail is actually a wrapper to
another MTA. The change will re-appear in a future
version.
SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X,
and SunOS 5.8. Requested by Jeff A. Earickson of Colby

Fix SMTP EXPN command output if the address expands to a single
name. Fix from John Beck of Sun Microsystems.
Don't try STARTTLS in the client if the PRNG has not been properly
seeded. This problem only occurs on systems without
/dev/urandom. Problem detected by Jan Krueger of
digitalanswers communications consulting gmbh and
Neil Rickert of Northern Illinois University.
Don't use the . and .. directories when expanding QueueDirectory
wildcards.
Do not try to cache LDAP connections across processes as a parent
process may close the connection before the child process
has completed. Problem noted by Lai Yiu Fai of the Hong
Kong University of Science and Technology and Wolfgang
Hottgenroth of UUNET.
Use Timeout.fileopen to limit the amount of time spent trying to
read the LDAP secret from a file.
Prevent SIGTERM from removing a command line submitted item after
the user submits the message and before the first delivery
attempt completes. Problem noted by Max France of AlphaNet.
Fix from Neil Rickert of Northern Illinois University.
Deal correctly with MaxMessageSize restriction if message size is
greater than 2^31.
Turn off queue checkpointing if CheckpointInterval is set to zero.
Treat an empty home directory (from getpw*() or $HOME) as
non-existent instead of treating it as /. Problem noted by
Todd C. Miller of Courtesan Consulting.
Don't drop duplicate headers when reading a queued item. Problem
noted by Motonori Nakamura of Kyoto University.
Avoid bogus error text when logging the savemail panic "cannot
save rejected email anywhere". Problem noted by Marc G.
Fournier of Acadia University.
If an LDAP search fails because the LDAP server went down, close
the map so subsequent searches reopen the map. If there are
multiple LDAP servers, the down server will be skipped and
one of the others may be able to take over.
Set the ${load_avg} macro to the current load average, not the
previous load average query result.
If a non-optional map used in a check_* ruleset can't be opened,
return a temporary failure to the remote SMTP client
instead of ignoring the map. Problem noted by Allan E
Johannesen of Worcester Polytechnic Institute.
Avoid a race condition when queuing up split envelopes by saving
the split envelopes before the original envelope.
Fix a bug in the PH_MAP code which caused mail to bounce instead of
defer if the PH server could not be contacted. From Mark
Roth of the University of Illinois at Urbana-Champaign.
Prevent QueueSortOrder=Filename from interfering with -qR, -qS, and
ETRN. Problem noted by Erik R. Leo of SoVerNet.
Change error code for unrecognized parameters to the SMTP MAIL and
RCPT commands from 501 to 555 per RFC 1869. Problem
reported to Postfix by Robert Norris of Monash University.
Prevent overwriting the argument of -B on certain OS. Problem
noted by Matteo Gelosa of I.NET S.p.A.
Use the proper routine for freeing memory with Netscape's LDAP
client libraries. Patch from Paul Hilchey of the
University of British Columbia.

CONFIG: Set confFROM_HEADER such that the mail hub can possibly add
GECOS information for an address. This more closely
matches pre-8.10 nullclient behavior. From Per Hedeland of
Ericsson.
CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for
SMTP to all *smtp* mailers and those for RELAY to the relay
mailer as described in cf/README.
MAIL.LOCAL: Open the mailbox as the recipient not root so quotas
are obeyed. Problem noted by Damian Kuczynski of NIK.
MAKEMAP: Do not change a map's owner to the TrustedUser if using
makemap to 'unmake' the map.
RMAIL: Avoid overflowing the list of recipients being passed to

TODO: STARTTLS support
--- 8.10.2 -> 8.11.0
8.11.0/8.11.0 2000/07/19
SECURITY: If sendmail is installed as a non-root set-user-ID binary
(not the normal case), some operating systems will still
keep a saved-uid of the effective-uid when sendmail tries
to drop all of its privileges. If sendmail needs to drop
these privileges and the operating system doesn't set the
saved-uid as well, exit with an error. Problem noted by
Kari Hurtta of the Finnish Meteorological Institute.
SECURITY: sendmail depends on snprintf() NUL terminating the string
it populates. It is possible that some broken
implementations of snprintf() exist that do not do this.
Systems in this category should compile with
-DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your
system and report broken implementations to
sendmail-bugs@sendmail.org and your OS vendor. Problem
noted by Slawomir Piotrowski of TELSAT GP.
Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS).
Implementation influenced by the example programs of
OpenSSL and the work of Lutz Jaenicke of TU Cottbus.
Add new STARTTLS related options CACERTPath, CACERTFile,
ClientCertFile, ClientKeyFile, DHParameters, RandFile,
ServerCertFile, and ServerKeyFile. These are documented in
cf/README and doc/op/op.*.
New STARTTLS related macros: ${cert_issuer}, ${cert_subject},
${tls_version}, ${cipher}, ${cipher_bits}, ${verify},
${server_name}, and ${server_addr}. These are documented
in cf/README and doc/op/op.*.
Add support for the Entropy Gathering Daemon (EGD) for better
random data.
New DontBlameSendmail option InsufficientEntropy for systems which
don't properly seed the PRNG for OpenSSL but want to
try to use STARTTLS despite the security problems.
Support the security layer in SMTP AUTH for mechanisms which
support encryption. Based on code contributed by Tim
Martin of CMU.
Add new macro ${auth_ssf} to reflect the SMTP AUTH security
strength factor.
LDAP's -1 (single match only) flag was not honored if the -z
(delimiter) flag was not given. Problem noted by ST Wong of
the Chinese University of Hong Kong. Fix from Mark Adamson
of CMU.
Add more protection from accidentally tripping OpenLDAP 1.X's
ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute().
Suggested by Kurt Zeilenga of OpenLDAP.
Fix the default family selection for DaemonPortOptions. As
documented, unless a family is specified in a
DaemonPortOptions option, "inet" is the default. It is
also the default if no DaemonPortOptions value is set.
Therefore, IPv6 users should configure additional sockets
by adding DaemonPortOptions settings with Family=inet6 if
they wish to also listen on IPv6 interfaces. Problem noted
by Jun-ichiro itojun Hagino of the KAME Project.
Set ${if_family} when setting ${if_addr} and ${if_name} to reflect
the interface information for an outgoing connection.
Not doing so was creating a mismatch between the socket
family and address used in subsequent connections if the
M=b modifier was set in DaemonPortOptions. Problem noted
by John Beck of Sun Microsystems.
If DaemonPortOptions modifier M=b is used, determine the socket
family based on the IP address. ${if_family} is no longer
persistent (i.e., saved in qf files). Patch from John Beck
of Sun Microsystems.
sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family}
macros for both the incoming interface address/family and
the outgoing interface address/family. In order for M=b
modifier in DaemonPortOptions to work properly, preserve
the incoming information in the queue file for later
delivery attempts.
Use SMTP error code and enhanced status code from check_relay in
responses to commands. Problem noted by Jeff Wasilko of
smoe.org.
Add more vigilance in checking for putc() errors on output streams
to protect from a bug in Solaris 2.6's putc(). Problem

If TryNullMXList is True and there is a temporary DNS failure
looking up the hostname, requeue the message for a later

Graeme Hewson of Oracle.
Avoid getting into an endless loop if a non-hoststat directory exists
within the hoststatus directory (e.g., lost+found).
Patch from Valdis Kletnieks of Virginia Tech.
Make sure Timeout.queuereturn=now returns a bounce message to the
sender. Problem noted by Per Hedeland of Ericsson.
If a message data file can't be opened at delivery time, panic and
