=========================================================================Ubuntu Security Notice USN-3846-1
December 20, 2018

linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-raspi2 vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10

Summary:

The system could be made to expose sensitive information.

Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
- linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
- linux-kvm: Linux kernel for cloud environments
- linux-raspi2: Linux kernel for Raspberry Pi 2

Details:

It was discovered that an integer overflow vulnerability existed in the
CDROM driver of the Linux kernel. A local attacker could use this to expose
sensitive information (kernel memory).

Update instructions:

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

Ubuntu 18.10:
  linux-image-4.18.0-1005-gcp     4.18.0-1005.6
  linux-image-4.18.0-1006-kvm     4.18.0-1006.6
  linux-image-4.18.0-1007-aws     4.18.0-1007.9
  linux-image-4.18.0-1007-azure   4.18.0-1007.7
  linux-image-4.18.0-1008-raspi2  4.18.0-1008.10
  linux-image-4.18.0-13-generic   4.18.0-13.14
  linux-image-4.18.0-13-generic-lpae  4.18.0-13.14
  linux-image-4.18.0-13-lowlatency  4.18.0-13.14
  linux-image-4.18.0-13-snapdragon  4.18.0-13.14
  linux-image-aws                 4.18.0.1007.7
  linux-image-azure               4.18.0.1007.8
  linux-image-gcp                 4.18.0.1005.5
  linux-image-generic             4.18.0.13.14
  linux-image-generic-lpae        4.18.0.13.14
  linux-image-gke                 4.18.0.1005.5
  linux-image-kvm                 4.18.0.1006.6
  linux-image-lowlatency          4.18.0.13.14
  linux-image-raspi2              4.18.0.1008.5
  linux-image-snapdragon          4.18.0.13.14

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.
