Second, if you don't know how to detect this, you shouldn't be running servers
He's right. Armed with the knowledge that it lives in /tmp and can be defeated with noexec, you should know how to find it with find, and moreover, I shouldn't have to tell you to use find.
However, if this shit is on your system, then you clearly shouldn't be running servers, because you are running antiques without proper supervision. Not running updates is seriously fringey behavior, especially when they are available free-of-charge.
