========================================================================== Ubuntu Security Notice USN-3819-1 November 14, 2018
linux, linux-aws, 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 crash or run programs as an administrator.
Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) 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:
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.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.10: linux-image-4.18.0-1003-gcp 4.18.0-1003.4 linux-image-4.18.0-1004-aws 4.18.0-1004.5 linux-image-4.18.0-1004-kvm 4.18.0-1004.4 linux-image-4.18.0-1006-raspi2 4.18.0-1006.8 linux-image-4.18.0-11-generic 4.18.0-11.12 linux-image-4.18.0-11-generic-lpae 4.18.0-11.12 linux-image-4.18.0-11-lowlatency 4.18.0-11.12 linux-image-4.18.0-11-snapdragon 4.18.0-11.12 linux-image-aws 4.18.0.1004.4 linux-image-gcp 4.18.0.1003.3 linux-image-generic 4.18.0.11.12 linux-image-generic-lpae 4.18.0.11.12 linux-image-gke 4.18.0.1003.3 linux-image-kvm 4.18.0.1004.4 linux-image-lowlatency 4.18.0.11.12 linux-image-raspi2 4.18.0.1006.3 linux-image-snapdragon 4.18.0.11.12
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.
