——————————————————————————–

Name : python-paramiko
Product : Fedora 26
Version : 2.2.3
Release : 1.fc26
URL : https://github.com/paramiko/paramiko
Summary : SSH2 protocol library for python
Description :

Paramiko (a combination of the Esperanto words for “paranoid” and “friend”) is
a module for python 2.3 or greater that implements the SSH2 protocol for secure
(encrypted and authenticated) connections to remote machines. Unlike SSL (aka
TLS), the SSH2 protocol does not require hierarchical certificates signed by a
powerful central authority. You may know SSH2 as the protocol that replaced
telnet and rsh for secure access to remote shells, but the protocol also
includes the ability to open arbitrary channels to remote services across an
encrypted tunnel. (This is how sftp works, for example.)

——————————————————————————–
Update Information:

A flaw was found in the implementation of `transport.py` in Paramiko, which did
not properly check whether authentication was completed before processing other
requests. A customized SSH client could simply skip the authentication step.
This flaw is a user authentication bypass in the SSH Server functionality of
Paramiko. Where Paramiko is used only for its client-side functionality (e.g.
`paramiko.SSHClient`), the vulnerability is not exposed and thus cannot be
exploited. This update also fixes an issue where Ed25519 auth key decryption
raised an unexpected exception when given a unicode password string (typical in
Python 3).
