Summary
USN-3443-1 fixed vulnerabilities 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.
It was discovered that on the PowerPC architecture, the kernel did not

possibly execute arbitrary code. (CVE-2017-1000255)
Andrey Konovalov discovered that a divide-by-zero error existed in the TCP
