Use CVE-2009-1373 for this one.

khc and I had a discussion about this one on IRC. It was decided it's a DoS
flaw only, my analysis is mostly right, other than the buffer is on the heap
via an alloca call, and the overflow won't cause anything outside of a crash.
Use CVE-2009-1374 for this.

This is not being considered a security flaw per our discussion on IRC (it
only reads 8 bytes off the stack, and does nothing with them).

datallah and I chatted about this one on IRC. It appears it's likely just a
DoS flaw, as all that happens is the buffer ends up corrupted in some manner,
perhaps a really clever attacker could inject some fake protocol bits to trick
a user, but that seems pretty far fetched.

Use CVE-2009-1376 for this.
What is the expected date for the release? I wouldn't mind a few more days if
you could spare it. I understand if you want this out sooner though, it's my
own fault I missed the mail.
