I was basically told that Facebook didn't see it as an issue and I was puzzled by that. Ends up the Facebook 
security team had issues reproducing my work and that's why they initially disgarded it. After publishing, the 
Facebook security team re-examined the issue and by working with me they seem to have been able to reproduce the bug.

Not fixed yet. At least not yesterday when I checked.
Nathan, didn't Facebook ask for some time to fix this bug after they have acknowledged it?

1. Summary:
When using the Facebook 'Messages' tab, there is a feature to attach a file.
Using this feature normally, the site won't allow a user to attach an executable file.
A bug was discovered to subvert this security mechanisms. Note, you do NOT have
to be friends with the user to send them a message with an attachment.
