Ubuntu 14.04 LTS / 16.04 LTS : Paramiko vulnerability (USN-3603-1)

critical Nessus Plugin ID 108514

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3603-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected python-paramiko and / or python3-paramiko packages.
