OpenSSH vulnerabilities in challenge response handling

- Date Updated: 27 Jun 2002
Caldera OpenLinux OpenSSH has neither the S/KEY nor BSD Auth features compiled in, so it is not vulnerable to the Challenge/Response vulnerability. We do have the ChallengeResponseAuthentication option on by default, however, so to be safe, we recommend that the option be disabled in the sshd_config file.
In addition, the sshd_config PAMAuthenticationViaKbdInt option is off by default, so OpenLinux is not vulnerable to the other alleged vulnerability in a default configuration, either. However, Caldera recommends that this option be disabled if it has been enabled by the system administrator.
The vendor has not provided us with any further information regarding this vulnerability.
