Ubuntu Security Notice USN-3630-2
April 24, 2018

linux-hwe, linux-gcp, linux-oem vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

The system could be made to crash under certain conditions.

Software Description:
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-hwe: Linux hardware enablement (HWE) kernel
- linux-oem: Linux kernel for OEM processors

Details:

USN-3630-1 fixed a vulnerability in the Linux kernel for Ubuntu 17.10.
This update provides the corresponding updates for the Linux Hardware
Enablement (HWE) kernel from Ubuntu 17.10 for Ubuntu 16.04 LTS.

It was discovered that the Broadcom UniMAC MDIO bus controller driver in
the Linux kernel did not properly validate device resources. A local
attacker could use this to cause a denial of service (system crash).

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
linux-image-4.13.0-1013-gcp 4.13.0-1013.17
linux-image-4.13.0-1024-oem 4.13.0-1024.27
linux-image-4.13.0-39-generic 4.13.0-39.44~16.04.1
linux-image-4.13.0-39-generic-lpae 4.13.0-39.44~16.04.1
linux-image-4.13.0-39-lowlatency 4.13.0-39.44~16.04.1
linux-image-gcp 4.13.0.1013.15
linux-image-generic-hwe-16.04 4.13.0.39.58
linux-image-generic-lpae-hwe-16.04 4.13.0.39.58
linux-image-gke 4.13.0.1013.15
linux-image-lowlatency-hwe-16.04 4.13.0.39.58
linux-image-oem 4.13.0.1024.28

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
