Multiple issues fixed in Ubuntu Linux kernel affecting several versions and derivatives, requiring critical updates.
Several security issues were fixed in the Linux kernel.

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-kvm: Linux kernel for cloud environments

- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

Lyu Tao discovered that the NFS implementation in the Linux kernel did not

properly handle requests to open a directory on a regular file. A local

attacker could use this to expose sensitive information (kernel memory).

Several security issues were discovered in the Linux kernel.

An attacker could possibly use these to compromise the system.

This update corrects flaws in the following subsystems:

- x86 architecture;

- ATM drivers;

- Device frequency scaling framework;

- GPU drivers;

- Hardware monitoring drivers;

- VMware VMCI Driver;

- MTD block device drivers;

- Network drivers;

- Device tree and open firmware driver;

- SCSI ...

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.
