Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-euclid: Linux kernel for Intel Euclid systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe: Linux hardware enablement (HWE) kernel - linux-kvm: Linux kernel for cloud environments - linux-oem: Linux kernel for OEM processors - linux-snapdragon: Linux kernel for Snapdragon processors - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty Details: Nick Peterson discovered that the Linux kernel did not properly handle debug exceptions following a MOV/POP to SS instruction. A local attacker could use this to cause a denial of service (system crash). This issue only affected the amd64 architecture. (CVE-2018-8897) Andy Lutomirski discovered that the KVM subsystem of the Linux kernel did not properly emulate the ICEBP instruction following a MOV/POP to SS instruction. A local attacker in a KVM virtual machine could use this to cause a denial of service (guest VM crash) or possibly escalate privileges inside of the virtual machine. This issue only affected the i386 and amd64 architectures. (CVE-2018-1087) Andy Lutomirski discovered that the Linux kernel did not properly perform error handling on virtualized debug registers. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-1000199) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.10: Ubuntu 16.04 LTS: Ubuntu 14.04 LTS: 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.
