Re: Cross Site Cooking

[john-secfocus () o-rourke org]

It's probably better referring to the cookies RFC (ftp://ftp.rfc-editor.org/in-notes/rfc2965.txt) rather than a very 
old article (http://www.ciac.org/ciac/bulletins/i-034.shtml).
The RFC doesn't mention anything about numbers of dots and specific domains.

Although it's all definitely a security risk, there's no way all vendors would change the mechanism without keeping 
backwards compatibility, it would cause chaos.  So with my sites I always put a checksum in the cookie data, which 
allows the website to be certain no clients have altered the data manually.
