Thanks for the heads-up.
I figured I'd check out Adobe's workaround :
http://www.adobe.com/support/security/bulletins/apsb07-18.html

... and there, in the section on registry editing to disable Acrobat's
mailto feature, we find the following :
> #  Navigate to the appropriate registry key:

And now I'm having heart palpitations ... can anyone explain the
function of the "telnet" and "ssh" parts of that little registry entry
?
