IMPORTANT: Read the install instructions before installing this upgrade.
Failure to do so will break ssh login capability.
MkLinux has just released a security upgrade for recent OpenSSH
vulnerabilities. This requires upgrading both OpenSSL and OpenSSH to
versions 0.9.6d and 3.4p1, respectively. These have been trivially
validated for basic operation. Some advanced features have not been fully
tested due to insufficient prior notice. This upgrade is strictly
use-at-your-own risk.
This upgrade fixes security holes in S/Key authentication and other
challenge-response authentication. Turning challenge-reponse support off
in the config file is a partial workaround that may be applied in lieu of
this update if you do not use that feature. However other security bugs
were also addressed in this update, so you should still upgrade if
possible.
Versions for MkLinux R1 and later are available now at
ftp://ftp.mklinux.org/pub/contrib/NOT_FOR_EXPORT/R1
Versions for MkLinux DR3 will be available when compilation completes at
ftp://ftp.mklinux.org/pub/contrib/NOT_FOR_EXPORT/DR3
