Canonical provides Kernel updates for all Ubuntu versions due to system security

This is the maximum kernel security update that Canonical provides for Ubuntu users. It mainly solves some security problems: allow non-privileged users to cause the denial-of-service system to gain Root user access. Canonical has provided Kernel updates for almost all Ubuntu systems, including Ubuntu14.04TrustyTahr, Ubuntu13.10SaucySalamander, Ubuntu12.10QuantalQuetzal, and Ubun.

It seems that this security issue involves a very far-reaching Ubuntu system. We recommend that you update the kernel of your Ubuntu system now!

We know that Ubuntu versions are driven by different kernel versions. This problem has been found to exist in all systems. At present, Ubuntu 14.04 is a reliable kernel version 3.small-24.47.

Linuxidc @ ubuntu :~ $Uname-
Linux ubuntu 3.small-24-generic# 46-Ubuntu SMP Thu Apr 10 19:08:14 UTC 2014 i686 i686 i686 GNU/Linux

At the same time, Ubuntu developers deleted another security threat to Ubuntu 14.04: allowing users to bypass the new lock screen.

To obtain the latest update, run the following command to perform a normal system upgrade:

Sudo apt-get update

Sudo apt-get dist-upgrade

106 software packages have been upgraded, 1 new software package has been installed, 0 software packages have been uninstalled, and 0 software packages have not been upgraded.
Download the 200 MB software package.
After decompression, 7,509 kB of extra space will be consumed.

Then restart the system:

Sudo reboot
