Has the launcher security issue in KDE and Gnome been fixed?

Hello,/p pI'm a Linux newbie, and one of the first things I heard about
Linux is that it doesn't get viruses (not specifically viruses, I mean any
kind of malware). Now, I see it can get malware through WINE and e-mail
(although I don't even open attachments or follow links from entities I
don't know). So, as far as this goes, one simply should use common sense
mattering the e-mails; and chose carefully what to run on WINE (and
possibly use a separate account for it)./p pLinux is further protected by
the fact all files are set to not be executable, so even if you get
malware, it can't execute. This was what I used to think, but it turns out
that in KDE and Gnome environments (AFAIK, this is what I read, it's from
2009, I don't know if it also happens elsewhere or if it was fixed) have
special treatment for something called launchers, that can only have one
command, but this may run a malicious script./p pI'd like to know exactly
why (if) launchers get special treatment (today and in 2009), how do they
look on the terminal (do they seem normal files; what happens if you enter
codels -l/code, etc.), and if this has received any attention from the
developers of these platforms./p pThanks for reading. BTW, I can try to
find the link from which I got this info if you would want to check it
out./p
