Synopsis
========

Unsafe randomness usage in Paramiko may allow access to sensitive
information.

Background
==========

Paramiko is a Secure Shell Server implementation written in Python.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /  Vulnerable  /                  Unaffected

  1  dev-python/paramiko       < 1.7.2                        >= 1.7.2

Description
===========

Dwayne C. Litzenberger reported that the file "common.py" does not
properly use RandomPool when using threads or forked processes.

Impact
======

A remote attacker could predict the values generated by applications
using Paramiko for encryption purposes, potentially gaining access to
sensitive information.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Paramiko users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-python/paramiko-1.7.2"
