Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS Summary: The system could be made to crash or run programs as an administrator. Software Description: - linux-azure: Linux kernel for Microsoft Azure Cloud systems Details: It was discovered that the KVM subsystem in the Linux kernel did not properly keep track of nested levels in guest page tables. A local attacker in a guest VM could use this to cause a denial of service (host OS crash) or possibly execute arbitrary code in the host OS. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 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.
