 Log Message:
 Update to 8.13.7; changelog below.  (8.13.6nb3 already had the security
 fixes by patch.)
 
 While here, fix PR pkg/33821 by substituting pkgsrc's BINOWN, BINGRP, and
 INSTALL definitions into the installed share/sendmail/cf/Makefile.
 
 8.13.7/8.13.7  2006/06/14
        A malformed MIME structure with many parts can cause sendmail to
                crash while trying to send a mail due to a stack overflow,
                e.g., if the stack size is limited (ulimit -s).  This
                happens because the recursion of the function mime8to7()
                was not restricted.  The function is called for MIME 8 to
                7 bit conversion and also to enforce MaxMimeHeaderLength.
                To work around this problem, recursive calls are limited to
                a depth of MAXMIMENESTING (20); message content after this
                limit is treated as opaque and is not checked further.
                Problem noted by Frank Sheiness.
        The changes to the I/O layer in 8.13.6 caused a regression for
                SASL mechanisms that use the security layer, e.g.,
                DIGEST-MD5.  Problem noted by Robert Stampfli.
        If a timeout occurs while reading a message (during the DATA phase)
                a df file might have been left behind in the queue.
                This was another side effect of the changes to the I/O
                layer made in 8.13.6.
        Several minor problems have been fixed that were found by a
                Coverity scan of sendmail 8 as part of the NetBSD
                distribution. See http://scan.coverity.com/
                Note: the scan generated also a lot of "false positives",
                e.g., "error" reports about situations that cannot happen.
                Most of those code places are marked with lint(1) comments
                like NOTREACHED, but Coverity does not understand those.
                Hence an explicit assertion has been added in some cases
                to avoid those false positives.
        If the start of the sendmail daemon fails due to a configuration
                error then in some cases shared memory segments or pid
                files were not removed.
        If DSN support is disabled via access_db, then related ESMTP
                parameters for MAIL and RCPT should be rejected.  Problem
                reported by Akihiro Sagawa.
        Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding
                bug work-around.  Hence if sendmail is linked against
                either of these versions and compression is available,
                the padding bug work-around is turned off.  Based on
                patch from Victor Duchovni of Morgan Stanley.
        CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used
                blackholes.mail-abuse.org as default domain for lookups,
                however, that list is no longer available.  To avoid
                further problems, no default value is available anymore,
                but an argument must be specified.
        Portability:
                Fix compilation on OSF/1 for sfsasl.c.  Patch from
                Pieter Bowman of the University of Utah.
