Synopsis

The remote Red Hat host is missing a security update for python-paramiko.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:3347 advisory.

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.

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