    ==========================================================================
    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.
