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.

Looks like its out there now:

Short version (correct me if I'm wrong):

If you have CUPS service cups-browsed on your machine and you for some reason exposed that to the internet (port 631), you are about to get pwned.

EDIT: It also requires the user to print to the malicious fake printer.

Yeah, what a disappointment. This guy brought shame to the security community because he was salty that his vulnerability didn't get the attention it "deserved".

Disappointment? Only if you mean the person that came up with FoomaticRIP.

For those who did not read the entire thing, it's a so called "filter" that converts the document before it's sent to certain nasty types of printers. Except it's not executed on the print server. The unauthenticated print server can just ask a client to run it on their side. And it's designed to be able to execute ANY command.
