high Nessus Plugin ID 118201

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3796-1 advisory.

Daniel Hoffman discovered that Paramiko incorrectly handled authentication when being used as a server. A remote attacker could use this issue to bypass authentication without any credentials.

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.
