OpenSSH vulnerabilities in challenge response handling

Status

Affected

Vendor Statement

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.
