Canonical Has Fixed Four Kernel Vulnerabilities, Upgrade Now

After releasing new Kernel stacks for Ubuntu 15.10 Wily Werewolf, Ubuntu 15.04 Vivid Vervet, Ubuntu 14.04 Trusty Tahr and Ubuntu 12.04 Precise Pangolin, Canonical has also updated the Kernel of Ubuntu 15.10 for Raspberry Pi 2.

Canonical has taken over the development of Kernel 4.2 and already patched four kernel vulnerabilities. The first flaw is regarding the PPP implementation, the second issue would permit a local attacker crash the system via a DoS (denial of service) attack. The third flaw was found in the kernel’s virtual video osd test driver, while the fourth was discovered in the kernel’s Digi Neo and ClassicBoard devices.

In order to keep your Ubuntu (or Ubuntu derivative system) safe, it is advised that you perform a regular system upgrade from now and then.

$ sudo apt-get update
$ sudo apt-get dist-upgrade

Reboot the system to use the new kernel:

$ sudo reboot
