Please consider that the probability that you describe above is likely
the wrong probability for this purpose.  The right one is the
cumulative probability that one of many images displayed over the
period of use of Emacs will realize the threat.  This probability is
evidently distressingly large in the proprietary[1] Windows world.

It is probably much smaller for Emacs users (but you'd need to study
their usage patterns in the light of the threat vectors to be sure).

[1]  Ie, people who use proprietary software almost exclusively, as
opposed to those who use free software except where employer demands
force them to use proprietary software.
