Ubuntu 16.04 LTS : linux-hwe, linux-azure, linux-gcp vulnerabilities (USN-3762-2)

Low Nessus Plugin ID 117455

Synopsis

The remote Ubuntu host is missing one or more security-related
patches.

Description

USN-3762-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 18.04 LTS for Ubuntu
16.04 LTS.

It was discovered that the VirtIO subsystem in the Linux kernel did
not properly initialize memory in some situations. A local attacker
could use this to possibly expose sensitive information (kernel
memory). (CVE-2018-1118)

Seunghun Han discovered an information leak in the ACPI handling code
in the Linux kernel when handling early termination of ACPI table
loading. A local attacker could use this to expose sensitive informal
(kernel address locations). (CVE-2017-13695).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution

Update the affected packages.
