New openssh packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, 10.2, 11.0, 12.0, and -current to fix a security issue.

Here are the details from the Slackware 12.0 ChangeLog:

patches/packages/openssh-5.0p1-i486-1_slack12.0.tgz: Upgraded to openssh-5.0p1. This version fixes a security issue where local users could hijack forwarded X connections. Upgrading to the new package is highly recommended. For more information on this security issue, please see: ( Security fix )

Installation instructions:

Upgrade the package as root: > upgradepkg openssh-5.0p1-i486-1_slack12.0.tgz

IMPORTANT NOTE: Before restarting sshd (if you use it), be sure to move any new /etc/rc.d/rc.sshd into place:

mv /etc/rc.d/ /etc/rc.d/rc.sshd

Then, make sure that the permissions are correct -- executable if you want sshd to start at boot, non-executable otherwise.

Finally, restart sshd:

sh /etc/rc.d/rc.sshd restart

This will restart the listener process so that all new connections to sshd will connect to the new sshd, while old connections will not be dropped (and may be insecure until they are disconnected and reattached). Any users who are forwarding X connections through ssh should drop their connection and log in again.
