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-4.15.0-1026-oem 4.15.0-1026.31
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.
