I'd suggest reading through the (many) comments about (more or less) this issue from the wp-hackers mailing list:
Search that page for "Security Vulnerability found", and you'll find some pertinent information. Note the threading on that site is not perfect; the issue is spread over a couple different threads.
I'm not trying to sidestep your question or to turn you away. I'm just pointing out some background. (And no apologies necessary).
EDIT: There was a forum post about the specific (so-called) threat that wp-hackers list thread talks about. http://wordpress.org/support/topic.php?id=30721
