Versions of MMGen prior to 0.9.7 were vulnerable to an attack whereby a
compromised MMGen installation on the network-connected machine could trick
an offline installation into revealing the user's seed via a specially crafted
transaction file.
Since sufficient time has passed for users to upgrade, we now deem it safe to
publish the exploit, implemented as a patch against v0.9.6. Instructions for
use are in the patch itself.
