Lisk v0.3.4 — Release Announcement



The latest Lisk client v0.3.4 has been released, and is now available for download via our downloads server. This version is a mandatory update, and is being released due to a critical transaction signature malleability issue found in the ed25519 implementation previously used by Lisk. Please note, in order to protect the network, all active delegates were patched prior to this release.

The implementation previously used: https://github.com/dazoe/ed25519, is based upon the default Ref10 specification, which does not check S<l when verifying signatures. This meant older transactions could be resent using a modified signature, S′=S+l. With this release v0.3.4, we have now switched our implementation to libsodium, which adds the necessary signature check. All node operators are therefore encouraged to update immediately.

An explanation of the issue is given here: http://crypto.stackexchange.com/questions/14712/non-standard-signature-security-definition-conforming-ed25519-malleability/14719#14719
