Not possible without rejecting the binary unfortunately. If you submitted it a day ago or so, just reject it. It'll get dropped down in the queue but if the situation calls for it, might be necessary.
In the same spot. We have multiple apps with updates, partly to get our keywords back together after the "Chomp" store search update. I had been hoping we'd get reviewed in the next day or two, but now I'm happy to wait a few more days so we don't hit this issue.
My update has been "waiting for review" for a week. I'm going to just let it proceed. When the update goes live I'll test it and if it's corrupted I'll just remove it from sale. Hopefully this will prevent users from updating. Then I'll email support and wait until the issue is resolved.
Don't play games with this one. If I were in your shoes, I'd pull my binary, too.
You do not want to be waiting on the App Store Review team to fix this. I'm one of the developers in Marco's post; it's been 24 hours and all I've gotten is a boilerplate response from the App Review team.
