ADVISORY - 22nd October 2016 - Update your Peppermint system.
« on: October 21, 2016, 08:27:07 pm »
Team Peppermint advise that all users update their systems to kernel 4.4.0-45.66 now.

You can update by clicking the "shield" icon in the system tray, then click the "Refresh" button, then once refreshed, click the "Install Updates" button .. once finished, REBOOT.

Another method is via the command line by running these commands in sequence:
Code: [Select]
sudo apt-get update
then
Code: [Select]
sudo apt-get dist-upgrade
then REBOOT.

Which ever method you choose, once rebooted run:
Code: [Select]
dpkg -l | grep linux-image-4.4.0-45-generic
which should list version 4.4.0-45.66 or later.

and
Code: [Select]
uname -a
should list version 4.4.0-45-generic #66 or later

This kernel fixes the vulnerability known as Dirty COW, which you can read about here:

... Alternatively, you can use the kernel tool in Update Manager: panel - View: Linux kernels

I love Update Manager.  :D
