NSA backdoor risks in Kerberos

[Chris Hecker]

I hope this won't turn into a giant thread, I'm just looking for some 
succinct facts and/or links to thoughtful discussion, I'm not interested 
in a bunch of opinions or a flame war or anything like that, and I don't 
think that'd be appropriate for this list or help anybody.  But here goes:

Has there been a technical writeup of potential backdoor risks in 
Kerberos, similar to the stuff that keeps coming out about various RSA 
products:

Thanks,
