Open disclosure - OpenPGP reports minor attack

In what looks like a nice piece of cryptanalysis, Serge Mister and Robert Zuccherato have found an oracle attack on OpenPGP. Don't worry, it's quite obscure - it would only effect automated systems that were prepared to handle a flood of messages, and it would only effect secret-key encrypted messages that the attacker has already got - something he only gets from your harddrive.

Fixing it is a bit more trouble, but it looks like a fix has been designed, and it will roll out in due course. The more interesting thing is that this sets a good precedent for getting things out in the open as soon as possible.
