New OpenSSH 3.4p1 packages providing privilege separation for improved
security are available for Slackware 7.1, 8.0, and 8.1. Here are the
details from the Slackware 8.1 ChangeLog:
- ----------------------------
Wed Jun 26 12:03:06 PDT 2002
patches/packages/openssh-3.4p1-i386-1.tgz: Upgraded to openssh-3.4p1.
This version enables privilege separation by default. The
README.privsep file says this about it:
Privilege separation, or privsep, is method in OpenSSH by which
operations that require root privilege are performed by a separate
privileged monitor process. Its purpose is to prevent privilege
escalation by containing corruption to an unprivileged process. More
information is available at:
http://www.citi.umich.edu/u/provos/ssh/privsep.html
Note that ISS has released an advisory on OpenSSH (OpenSSH Remote
Challenge Vulnerability). Slackware is not affected by this issue, as
we have never included AUTH_BSD, S/KEY, or PAM. Unless at least one of
these options is compiled into sshd, it is not vulnerable. Further note
that none of these options are turned on in a default build from source
code, so if you have built sshd yourself you should not be vulnerable
unless you've enabled one of these options.
Regardless, the security provided by privsep is unquestionably better.
This time we (Slackware) were lucky, but next time we might not be.
Therefore we recommend that all sites running the OpenSSH daemon (sshd,
enabled by default in Slackware 8.1) upgrade to this new openssh
package. After upgrading the package, restart the daemon like this:
/etc/rc.d/rc.sshd restart
We would like to thank Theo and the rest of the OpenSSH team for their
quick handling of this issue, Niels Provos and Markus Friedl for
implementing privsep, and Solar Designer for working out issues with
privsep on 2.2 Linux kernels.

INSTALLATION INSTRUCTIONS:
- --------------------------
First upgrade the OpenSSH package:
# upgradepkg openssh-3.4p1-i386-1.tgz
Then, check the /etc/ssh/ directory where the new config files will be
installed as ssh_config.new and sshd_config.new. Most sites will want
to move these on top of the existing config files:
# mv ssh_config.new ssh_config
# mv sshd_config.new sshd_config
Finally, restart the sshd daemon:
# . /etc/rc.d/rc.sshd restart
