Subject: Caldera Security Advisory SA-1997.10: Security updates to sendmail
Caldera Security Advisory SA-1997.10
Original report date: 14-Jun-1997
RPM build date: 16-Jun-1997
Original issue date: 22-Jul-1997
Last revised: 22-Jul-1997
Topic: Security updates to sendmail
I. Problem Description
Sendmail 8.8.6 has been released. This version contains many
bug fixes (and no new features). A few of these fixes are
security related, although most of these are specific to unusual
circumstances (e.g., obsolete versions of HP-UX that didn't
implement the O_EXCL open bit properly, or problems resulting from
systems that put database maps into world writable directories).
Complete RELEASE_NOTES for this release are included in the source
RPM.
II. Impact
The list of changes in this release is long. As mentioned above,
most are not security related. But those that are security related
are documented in the lengthy RELEASE_NOTES file that can be found
in the source RPM.
III. Solution
Install the new sendmail 8.8.6 packages, as described below.
These packages are located on Caldera's FTP server (ftp.caldera.com):
ftp://ftp.caldera.com/pub/openlinux/updates/1.1/current/
The MD5 checksum (from the "md5sum" command) for these package are:
0360c84a4e69ac78f8512659c2012441 RPMS/sendmail-8.8.6-1.i386.rpm
d73d10ed515a39f8218af6c9599313a5 RPMS/sendmail-cf-8.8.6-1.i386.rpm
a6b771657f9e7203f9217ab84cce4007 RPMS/sendmail-doc-8.8.6-1.i386.rpm
e6b89f61566ef69b3d3ccfaa9a0b7bff SRPMS/sendmail-8.8.6-1.src.rpm
Please follow these instructions precisely to update any older
version of sendmail that may be on your system:
/etc/rc.d/init.d/mta stop
rpm -q sendmail-doc && rpm -U RPMS/sendmail-doc-8.8.6-1.i386.rpm
rpm -q sendmail-cf && rpm -U RPMS/sendmail-cf-8.8.6-1.i386.rpm
rpm -e sendmail && rpm -i RPMS/sendmail-8.8.6-1.i386.rpm
[ -e /etc/sendmail.cf.rpmsave ] && echo "configuration changed..."
/etc/rc.d/init.d/mta start
Note: One must perform the updates in the order shown above to avoid
having rpms conflict during the upgrade.
Note: The warning message
"cannot remove /usr/share/sendmail - directory not empty"
during installation of sendmail-cf can be safely ignored.
Note: /etc/sendmail.cf has changed quite a bit -- overwriting it with
a potential /etc/sendmail.cf.rpmsave is NOT a viable option! Previous
changes have to be re-applied (preferably with m4 and .mc files).
