                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           openssh
Advisory ID:            MDKSA-2002:040
Date:                   June 24th, 2002
Affected versions:      7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1,
                        Single Network Firewall 7.2

Problem Description:

 Details of an upcoming OpenSSH vulnerability will be published early
 next week.  According to the OpenSSH team, this remote vulnerability
 cannot be exploited when sshd is running with privilege separation.
 The priv separation code is significantly improved in version 3.3 of 
 OpenSSH which was released on June 21st.  Unfortunately, there are some
 known problems with this release; compression does not work on all
 operating systems and the PAM support has not been completed.

 The OpenSSH team encourages everyone to upgrade to version 3.3
 immediately and enable privilege separation.  This can be enabled by
 placing in your /etc/ssh/sshd_config file the following:

   UsePrivilegeSeparation yes

 The vulnerability that will be disclosed next week is not fixed in
 version 3.3 of OpenSSH, however with priv separation enabled, you will
 not be vulnerable to it.  This is because privilege separation uses a
 seperate non-privileged process to handle most of the work, meaning
 that any vulnerability in this part of OpenSSH will never lead to a
 root compromise.  Only access as the non-privileged user restricted in
 chroot would be available.

 MandrakeSoft encourages all of our users to upgrade to the updated
 packages immediately.  This update creates a new user and group on the
 system named sshd that is used to run the non-privileged processes.
