The hostname parsing in the DNS parser will return an error when it runs out of data instead of incomplete. This can result in a specially crafted DNS payload not being detected as DNS.

Fix with master (nom7) is trivially done by moving error handling to the question mark operator. Its likely the same is true for 5.0.x and 6.0.x. This will probably ripple up incomplete or error up the parse chain.
