ubuntu
Calendar Grey August 13, 2019
Dist Ubuntu Esm H88
A range of security flaws were addressed in the Linux kernel for Ubuntu 14.04 ESM; important patches have been released.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

USN-4095-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04

LTS. This update provides the corresponding updates for the Linux

Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu

14.04 ESM.

Eli Biham and Lior Neumann discovered that the Bluetooth implementation in

the Linux kernel did not properly validate elliptic curve parameters during

Diffie-Hellman key exchange in some situations. An attacker could use this

to expose sensitive information. (CVE-2018-5383)

It was discovered that a heap buffer overflow existed in the Marvell

Wireless LAN device driver for the Linux kernel. An attacker could use this

to cause a denial of service (system crash) or possibly execute arbitrary

code. (CVE-2019-10126)

Andrei Vlad Lutas and Dan Lutas d...

Update Instructions

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

Ubuntu 14.04 ESM:
  linux-image-4.4.0-1050-aws      4.4.0-1050.54
  linux-image-4.4.0-159-generic   4.4.0-159.187~14.04.1
  linux-image-4.4.0-159-generic-lpae  4.4.0-159.187~14.04.1
  linux-image-4.4.0-159-lowlatency  4.4.0-159.187~14.04.1
  linux-image-4.4.0-159-powerpc-e500mc  4.4.0-159.187~14.04.1
  linux-image-4.4.0-159-powerpc-smp  4.4.0-159.187~14.04.1
  linux-image-4.4.0-159-powerpc64-emb  4.4.0-159.187~14.04.1
  linux-image-4.4.0-159-powerpc64-smp  4.4.0-159.187~14.04.1
  linux-image-aws                 4.4.0.1050.51
  linux-image-generic-lpae-lts-xenial  4.4.0.159.140
  linux-image-generic-lts-xenial  4.4.0.159.140
  linux-image-lowlatency-lts-xenial  4.4.0.159.140
  linux-image-powerpc-e500mc-lts-xenial  4.4.0.159.140
  linux-image-powerpc-smp-lts-xenial  4.4.0.159.140
  linux-image-powerpc64-emb-lts-xenial  4.4.0.159.140
  linux-image-powerpc64-smp-lts-xenial  4.4.0.159.140
  linux-image-virtual-lts-xenial  4.4.0.159.140

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.
