Canonical has just announced that the company has collected microcode updates of Intel processors in all its supporting versions of the Ubuntu Linux distribution repository, in order to mitigate the impact of Spectre security vulnerabilities. A processor security vulnerability that has been exposed earlier can cause an attacker without a privileged access to access to kernel memory. In view of this, Canonical recommends that customers upgrade the corresponding Linux kernel version as soon as possible, such as Ubuntu 17.10 (Artful Aardvark), Ubuntu 17.04 (Zesty Zapus), Ubuntu 16.04 LTS (Xenial Xerus), as well as 14.04 14.04.

Canonical wrote in the Security Bulletin:

It is found that a microprocessor has a security hazard in predictive execution and predictive execution, or allows unauthorized people to bypass attacks to read memory

A local attacker can take sensitive information, including kernel memory (Bulletin number:CVE-2017-5715).

To update the Intel CPU microcode, please pay attention to downloading the corresponding version:

The new version for Ubuntu 17.10 is

The new version for Ubuntu 17.10 is

The microcode update installation method is as follows:
