Hello Linux Geeksters. Canonical has fixed three security vulnerabilities for Ubuntu 13.04 Raring Ringtail, twelve security issues found on Ubuntu 12.04 Precise Pangolin and two vulnerabilities for Ubuntu 10.04 Lucyd Linx.
After the upgrade, you will get kernel 3.8.0-34.49 on Ubuntu 13.04, kernel 3.2.0-57.87 on Ubuntu 12.04 and kernel 2.6.32-54.116 on Ubuntu 10.04.
To get the Kernel updates for Ubuntu 13.04, Ubuntu 12.04 and Ubuntu 10.04, all you have to do is perform a normal system upgrade. Like this:
$ sudo apt-get update
$ sudo apt-get dist-upgrade
And reboot after the upgrade has performed successfully.
