Statement

This flaw is a user authentication bypass in the SSH Server functionality of paramiko (normally used by subclassing paramiko.ServerInterface). Where paramiko is used only for its client-side functionality (e.g. paramiko.SSHClient), the vulnerability is not exposed and thus cannot be exploited.

The following Red Hat products use paramiko only in client-side mode. Server side functionality is not used.
