USN-3603-1 fixed a vulnerability in Paramiko. This update provides
the corresponding update for Ubuntu 12.04 ESM.

Original advisory details:

unauthenticated remote attacker could possibly use this to execute
arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

After a standard system update you need to restart any applications
using Paramiko's server implementation to make all the necessary changes.
