SERIOUS VULNERABILITY related to accepting zero-confirmation transactions January 12, 2013, 03:17:47 AM #1 Quote from: retep on January 11, 2013, 11:14:37 PM If you do not accept zero-confirmation transactions this vulnerability does not affect you.



However if you do be advised that a previously unknown coin-stealing attack has been found that allows zero-confirmation transactions to be double-spent with a trivial amount of effort and without having to have access to any mining capacity.



Details will be release as soon as a patch is ready. In the meantime do not accept any transaction without at least one confirmation unless you fully trust the sender not to defraud you.



Mods: please copy this to important announcements.
