I believe they've patched it already. But if you haven't updated the updater yet, you're probably still vulnerable.

The posting says that the patch is not very good, but that's a separate issue.

On my machine the Blizzard launcher only checks for updates and updates itself when you run it so if you have it installed but haven't run it in a while you might not have the most recent.
