Bug 253780 is confidential because it contains a reduced testcase explaining how to implement the exploit. By the way, it isn't quite the same thing as bug 240246, which itself wouldn't mind being confidential, though it's a bit late for that. *** This bug has been marked as a duplicate of 253780 ***

Should this one be reopened to cut down on duplicate reports?

Might be wise. I'm just trying to minimize the noise. How 'bout when the next one comes in, we leave that open? I have some notion that it'll be a while.
