SENDMAIL RELEASE NOTES
@(#)RELEASE_NOTES 8.8.4.4 (Berkeley) 12/2/96
@(#)RELEASE_NOTES 8.8.5.3 (Berkeley) 1/21/97
This listing shows the version of the sendmail binary, the version
of the sendmail configuration files, the date of release, and a
summary of the changes in that release.
8.8.5/8.8.5 97/01/21
SECURITY: Clear out group list during startup. Without this, sendmail
will continue to run with the group permissions of the caller,
even if RunAsUser is specified.
SECURITY: Make purgestat (-bH) be root-only. This is not in response
to any known attack, but it's best to be conservative.
Suggested by Peter Wemm of DIALix.
SECURITY: Fix buffer overrun problem in MIME code that has possible
security implications. Patch from Alex Garthwaite of the
University of Pennsylvania.
Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'")
would truncate the address after "Full". Although the -f
syntax is incorrect (since it is in the envelope, it
shouldn't have comments and full names), the failure mode
was unnecessarily awful.
Fix a possible null pointer dereference when converting 8-bit data
to a 7-bit format. Problem noted by Jim Hutchins of
Sandia National Labs and David James of British Telecom.
Clear out stale state that affected F=9 on SMTP mailers in queue
runs. Although this really shouldn't be used (F=9 is for
final delivery only, and using it on an SMTP mailer makes
it possible for a message to be converted from 8->7->8->7
bits several times), it shouldn't have failed with a syserr.
Problem noted by Eric Hagberg of Morgan Stanley.
_Really_ fix the multiple :maildrop code in the user database
module. Patch from Roy Mongiovi of Georgia Tech.
Let F lines in the configuration file actually read root-only
files if the configuration file is safe. Based on a
patch from Keith Reynolds of SCO.
ETRN followed by QUIT would hold the connection open until the queue
run completed. Problem noted by Truck Lewis of TDK
Semiconductor Corp.
It turns out that despite the documentation, the TCP wrappers library
does _not_ log rejected connections. Do the logging ourselves.
Problem noted by Fletcher Mattox of the University of Texas
at Austin.
If sendmail finds a qf file in its queue directory that is an unknown
version (e.g., when backing out to an old version), the
error is reported on every queue run. Change it to only
give the error once (and rename the qf => Qf). Patch from
William A. Gianopoulos of Raytheon Company.
Start a new session when doing background delivery; currently it
ignored signals but didn't start a new signal, that caused
some problems if a background process tried to send mail
under certain circumstances. Problem noted by Eric Hagberg
of Morgan Stanley; fix from Kari Hurtta.
Simplify test for skipping a queue run to just check if the current
load average is >= the queueing load average. Previously
the check factored in some other parameters that caused it
to essentially never skip the queue run. Patch from Bryan
Costales.
If the SMTP server is running in "nullserver" mode (that is, it is
rejecting all commands), start sleeping after MAXBADCOMMAND
(25) commands; this helps prevent a bad guy from putting
you into a tight loop as a denial-of-service attack. Based
on an e-mail conversation with Brad Knowles of AOL.
Slow down when too many "light weight" commands have been issued;
this helps prevent a class of denial-of-service attacks.
The current values and defaults are:
MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR
MAXHELOCOMMANDS 3 HELO, EHLO
MAXVRFYCOMMANDS 6 VRFY, EXPN
MAXETRNCOMMANDS 8 ETRN
These will probably be configurable in a future release.
On systems that have uid_t typedefed to be an unsigned short, programs
that had the F=S flag and no U= equate would be invoked with
the real uid set to 65535 rather than being left unchanged.
In some cases, NOTIFY=NEVER was not being honored. Problem noted
by Steve Hubert of the University of Washington, Seattle.
Mail that was Quoted-Printable encoded and had a soft line break on
the last line (i.e., an incomplete continuation) had the last
line dropped. Since this appears to be illegal it isn't
clear what to do with it, but flushing the last line seems
to be a better "fail soft" approach. Based on a patch from
Eric Hagberg.
If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a
bogus HELO command still causes the "Polite people say HELO
first" error message. Problem pointed out by Chris Thomas
of UCLA; patch from John Beck of SunSoft.
Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set
in PrivacyFlags. The -q shouldn't turn this command off.
Problem noted by Murray Kucherawy of Pacific Bell Internet;
based on a patch from Gregory Neil Shapiro of WPI.
Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation)
in a DATA transaction to be sticky; these can occur because
a message is too large, and smaller messages should still go
through. Problem noted by Matt Dillon of Best Internet
Communications.
In some cases bounces were saved in /var/tmp/dead.letter even if they
had been successfully delivered to the envelope sender.
Problem noted Eric Hagberg of Morgan Stanley; solution from
Gregory Neil Shapiro of WPI.
Give better diagnostics on long alias lines. Based on code contributed
by Patrick Gosling of the University of Cambridge.
Increase the number of virtual interfaces that will be probed for
alternate names. Problem noted by Gregory Neil Shapiro of
WPI.
PORTABILITY:
UXP/DS V20L10 for Fujitsu DS/90: Makefile patches from
Toshiaki Nomura of Fujitsu Limited.
SunOS with LDAP support: compile problems with struct timeval.
Patch from Nick Cuccia of TCSI Corporation.
SCO: from Keith Reynolds of SCO.
Solaris: kstat load average computation wasn't being used.
Fixes from Michael Ju. Tokarev of Telecom Service, JSC
(Moscow).
OpenBSD: from Jason Downs of teeny.org.
Altos System V: from Tim Rice.
Solaris 2.5: from Alan Perry of SunSoft.
Solaris 2.6: from John Beck of SunSoft.
Harris Nighthawk PowerUX (mh6000 box): from Bob Miorelli
of Pratt & Whitney <miorelli@pweh.com>.
CONFIG: It seems that I hadn't gotten the Received: line syntax
_just_right_ yet. Tweak it again. I'll omit the names
of the "contributors" (quantity two) in this one case.
As of now, NO MORE DISCUSSION about the syntax of the
Received: line.
CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E),
it never inserts that class into the output file. Fix it
so it will honor EXPOSED_USER but will _not_ include root
automatically in this class. Problem noted by Ronan KERYELL
of Centre de Recherche en Informatique de l'École Nationale
Supérieure des Mines de Paris (CRI-ENSMP).
CONFIG: Clean up handling of "local:" syntax in relay specifications
such as LUSER_RELAY. This change permits the following
syntaxes: ``local:'' will send to the same user on the
local machine (e.g., in a mailertable entry for "host",
``local:'' will cause an address addressed to user@host to
go to user on the local machone). ``local:user'' will send
to the named user on the local machine. ``local:user@host''
is equivalent to ``local:user'' (the host is ignored). In
all cases, the original user@host is passed in $@ (i.e., the
detail information). Inspired by a report from Michael Fuhr
of Dimensional Communications, L.L.C.
CONFIG: Strip quotes from the first word of an "error:" host
indication. This lets you set (for example) the LUSER_RELAY
to be ``error:\"5.1.1\" Your Message Here''. Note the use
of the \" so that the resulting string is properly quoted.
Problem noted by Gregory Neil Shapiro of WPI.
OP.ME: documentation was inconsistent about whether sendmail did a
NOOP or a RSET to probe the connection (it does a RSET).
Inconsistency noted by Deeran Peethamparam.
OP.ME: insert additional blank pages so it will print properly on
a duplex printer. From Matthew Black of Cal State University,
Long Beach.

permissions by hard linking to files that were group
