1. Problem Summary

If the UseLogin feature is enabled in ssh local users could pass
environment variables to the login process.

2. Impact

A user can gain root privileges.

3. Solution

This has been fixed by not copying the environment if UseLogin is enabled.

Update the following packages from our ftp server
by running the following command:

rpm -Uvh ftp://ftp.turbolinux.com/pub/updates/6.0/security/<rpm>

Where <rpm> are the following:

openssl-0.9.6b-1.i386.rpm
openssl-devel-0.9.6b-1.i386.rpm
openssh-2.9p2-6.i386.rpm
openssh-askpass-2.9p2-6.i386.rpm
openssh-askpass-gnome-2.9p2-6.i386.rpm
openssh-clients-2.9p2-6.i386.rpm
openssh-sever-2.9p2-6.i386.rpm


The source RPM can be downloaded from:

ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/openssl-0.9.6b-1.src.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/openssh-2.9p2-6.src.rpm

**Note: You must rebuild and install the RPM if you choose to download
and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE
THE SECURITY HOLE.

Please verify the MD5 checksums of the updates before you install:
