Here's a common vector that could be used for Ubuntu:

"Hey everybody, I just made updated firefox/pidgin/etc packages in my
ppa! Let me know how they work!"

Adding a PPA is down to a single command, they are GPG signed so as to
avoid popping up security errors, and can provide any package (say,
firefox and gksudo). Furthermore, the firefox package may itself provide
extra files, or a postinst script that replaces gksudo (or any other
file) with a modified version. etc.
