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.
The following packages have been upgraded to a later upstream version:
python-paramiko (2.1.1). (BZ#1562393)
* python-paramiko: Authentication bypass in transport.py (CVE-2018-7750)
