Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-3404-2 advisory.

 USN-3404-1 fixed a vulnerability in the Linux kernel for Ubuntu 17.04. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 17.04 for Ubuntu 16.04 LTS.
