CentOS Errata and Security Advisory CESA-2018:3406

The python-paramiko package provides a Python module that implements the SSH2 protocol for encrypted and authenticated connections to remote machines. Unlike SSL, the SSH2 protocol does not require hierarchical certificates signed by a powerful central authority. The protocol also includes the ability to open arbitrary channels to remote services across an encrypted tunnel.

Security Fix(es):

  • python-paramiko: Authentication bypass in auth_handler.py (CVE-2018-1000805)
