DESCRIPTION:
A weakness has been reported in paramiko, which can be exploited by
malicious people to disclose potentially sensitive information.

The weakness is caused due to an error when using the "RandomPool"
class to generate random numbers simultaneously in multiple threads
or child processes. This can potentially be exploited to disclose
sensitive information transmitted through paramiko connections.

The weakness is reported in version 1.6.4. Other versions may also be
affected.

SOLUTION:
Do not rely on the security provided by paramiko when encrypting
multiple network connections simultaneously.
