Ubuntu Security Notice USN-3603-1
March 20, 2018
paramiko vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 17.10
– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS
Summary:
Paramiko could be made to run programs if it received specially
crafted network traffic.
Software Description:
– paramiko: Python SSH2 library
Details:
Matthijs Kooijman discovered that Paramiko’s SSH server implementation
did not properly require authentication before processing requests. An
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:
Ubuntu 17.10:
python-paramiko 2.0.0-1ubuntu0.1
python3-paramiko 2.0.0-1ubuntu0.1
Ubuntu 16.04 LTS:
python-paramiko 1.16.0-1ubuntu0.1
python3-paramiko 1.16.0-1ubuntu0.1
Ubuntu 14.04 LTS:
python-paramiko 1.10.1-1git1ubuntu0.1
After a standard system update you need to restart any applications
using Paramiko’s server implementation to make all the necessary changes.
