Affected configurations: cpp-ethereum (eth, AlethZero, …) model 1.2.0 as much as 1.2.6
Be aware: Neither “geth” nor “Mist” nor the “Ethereum Pockets” (except explicitly used along with cpp-ethereum) are affected by this, they lock accounts accurately once more.
That is only a fast head’s up that cpp-ethereum’s security issue around account security shouldn’t be but correctly fastened. The repair that’s a part of cpp-ethereum model 1.2.6 didn’t lower the safety, nevertheless it additionally didn’t repair the bug utterly. We are going to work in direction of one other bugfix launch and announce it as soon as the repair is correctly verified.
A repair is now obtainable: Launch 1.2.7 – https://github.com/ethereum/webthree-umbrella/releases/tag/v1.2.7
