critical Nessus Plugin ID 101929

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3361-1 advisory.

 USN-3358-1 fixed vulnerabilities in the Linux kernel for Ubuntu 17.04.
