Critical vulnerability affecting most Linux distros allows for bootkits
(arstechnica.com)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

2 scenarios where it can be exploited:
Acquiring the ability to compromise a server or perform an adversary-in-the-middle impersonation of it to target a device that’s already configured to boot using HTTP
Already having physical access to a device or gaining administrative control by exploiting a separate vulnerability.
