These launchers cannot execute arbitrary code. You can click on them of course. Whether something bad happens then is a different problem, and because a DE is nowadays getting more and more capable of turning code into a running process, this does require some attention from developers and users alike.

But, since launchers are not only special files to the DE interpreter, but also files on my filesystem and therefore interpretable by my shells, I prefer them to NOT be ordinary executables, shell scripts, Perl files or anything that can be run outside of the desktop environment.

Note that I am not saying that the typical desktop is a very safe place. Here, the problem seems to be that they can be run from different places within a desktop environment, which is not a brilliant idea. The solution is to keep things more separate: you will really not likely find ls(1) in /home/cracker.

All this, of course, has very little to do with serious security threats and defense mechanisms.
