This post The Terminal Escapes: Engineering unexpected execution from command line interfaces has a summary of the longer paper in the first link.

tldr: There are a variety of ways that attackers can cause you to execute execute arbitrary code when you echo their maliciously-crafted data to your terminal. Therefore, when you run curl without redirecting its output, or when you cat a file you've downloaded, you're trusting the server (and also the network, when you don't have https:// in the url) not to exploit you.

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.
