Severity: Low
Title: Paramiko: Information disclosure
Date: March 03, 2008
Bugs: #205777
ID: 200803-07


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 &quot;&gt;=dev-python/paramiko-1.7.2&quot;
