Potential pitfalls in DNS handling
Posted Nov 16, 2012 19:11 UTC (Fri) by hawk (subscriber, #3195)
This article is really about what kind of data you can get back in a (still correctly formatted) DNS response. It's important to note that even though the DNS protocol can carry anything there may still be application specific naming rules that prevents the full-on "any byte is valid" in a specific context.
(The article does have an unfortunate mixup (that's my take on it, anyway) where hostname name rules and DNS protocol name rules seem to be considered the same thing. See my comment regarding this: http://lwn.net/Articles/525471/)

Note that everything the protocol can transport might be a superset of what the protocol allows.
