Hardly news/vulnerability since reverse DNS is rarely reliable, and even when it works people commonly do things like www1, www2, www3, etc. Even if Sonic wall did everything, any website without reverse DNS would still be reachable unless you start blocking IP's. Names are for convenience, they are not terribly reliable for identifying things you want to block on the web.
