It's not clear, which makes me skeptical that this is all that serious of an issue.
I'd like to know - can any devices actually put such a malformed message onto the carrier network? It probably requires at least a custom app that would never be allowed on an app store, if it's possible at all. And do any carriers actually let it go through their network and to a device like a normal message? It's entirely possible the malformed message would crash some software in the carrier's processing stack first and so never be delivered. And if it doesn't, they could easily add a check to block such messages. It's difficult to believe they don't already have some sort of protection against spamming tons of messages to any device. It's also entirely possible it works differently on different carriers, and some but not others might add blocks for this but not make a press release about it or anything.
This seems more like meh, minor bug, fix it quietly in the next Android release, not OMG the world is on fire to me.
