    Ubuntu Security Notice USN-3820-1
    November 14, 2018
    
    linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-oem, linux-raspi2 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.04 LTS
    
    Summary:
    
    Several security issues were fixed in the Linux kernel.
    
    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-oem: Linux kernel for OEM processors
    - linux-raspi2: Linux kernel for Raspberry Pi 2
    
    Details:
    
    Felix Wilhelm discovered that the Xen netback driver in the Linux kernel
    did not properly perform input validation in some situations. An attacker
    could use this to cause a denial of service (system crash) or possibly
    execute arbitrary code. (CVE-2018-15471)
    
    It was discovered that the generic SCSI driver in the Linux kernel did not
    properly enforce permissions on kernel memory access. A local attacker
    could use this to expose sensitive information or possibly elevate
    privileges. (CVE-2017-13168)
    
    It was discovered that an integer overflow existed in the CD-ROM driver of
    the Linux kernel. A local attacker could use this to expose sensitive
    information (kernel memory). (CVE-2018-16658)
    
    It was discovered that an integer overflow existed in the HID Bluetooth
    implementation in the Linux kernel that could lead to a buffer overwrite.
    An attacker could use this to cause a denial of service (system crash) or
    possibly execute arbitrary code. (CVE-2018-9363)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.04 LTS:
      linux-image-4.15.0-1024-gcp     4.15.0-1024.25
      linux-image-4.15.0-1026-kvm     4.15.0-1026.26

      linux-image-4.15.0-1027-aws     4.15.0-1027.27
      linux-image-4.15.0-1028-raspi2  4.15.0-1028.30
      linux-image-4.15.0-1031-azure   4.15.0-1031.32
      linux-image-4.15.0-39-generic   4.15.0-39.42
      linux-image-4.15.0-39-generic-lpae  4.15.0-39.42
      linux-image-4.15.0-39-lowlatency  4.15.0-39.42
      linux-image-4.15.0-39-snapdragon  4.15.0-39.42
      linux-image-aws                 4.15.0.1027.27
      linux-image-azure               4.15.0.1031.31
      linux-image-gcp                 4.15.0.1024.26
      linux-image-generic             4.15.0.39.41
      linux-image-generic-lpae        4.15.0.39.41
      linux-image-gke                 4.15.0.1024.26
      linux-image-kvm                 4.15.0.1026.26
      linux-image-lowlatency          4.15.0.39.41
      linux-image-oem                 4.15.0.1026.31
      linux-image-raspi2              4.15.0.1028.26
      linux-image-snapdragon          4.15.0.39.41
    
    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.
