Subject: Bugtraq Security Systems XMAS Advisory 0001

I have to admit that I'm confused. To the best of my knowledge I was 
never contacted with regards to anything relating squirrel mail, nor do 
I have any affiliation or association with the squirrelmail team or 
their product. Perhaps this is something OSX related? If that's so you 
might want to do a rockin' advisory around this.

The reference to black v white hat also has me perplexed as it seems to 
be in part directed towards myself. Not following the relevance to the 
advisory being put aside, I always preferred the term grey-hat for 
similar reasons to those you mention. Who has ever lived in a black and 
white world?

If I'm missing something (quite possible) in regards to an issue I am 
in a situation to help improve please drop me a note.

cheers,

.mudge

PS - thanks for the 'rock-star' label... but if that's the case my 
question is: "where are all the beautiful groupies?"
