Hi gang, Rob from The MagPi here. We have a new issue out on Thursday but before that, here comes a PSA.
You may have seen the news recently about a bug in the Linux kernel called Dirty COW – it’s a vulnerability that affects the ‘copy-on-write’ mechanism in Linux, which is also known as COW. This bug can be used to gain full control over a device running a version of Linux, including Android phones, web servers, and even the Raspberry Pi.
You don’t need to worry though, as a patch for Raspbian Jessie to fix Dirty COW has already been released, and you can get it right now. Open up a terminal window and type the following:
sudo apt-get update sudo apt-get install raspberrypi-kernel
Once the install is done, make sure to reboot your Raspberry Pi and you’ll be Dirty COW-free!
