Full Disclosure: Re: Facebook Attach EXE Vulnerability

[Nathan Power <np () securitypentest com>]

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.
