Overview

github.com/tendermint/tendermint/p2p/conn is a p2p connection package part of tendermint.

Affected versions of this package are vulnerable to Man in The Middle (MiTM). The MakeSecretConnection function has a bug which allows a third party to MITM the connection and decrypt/modify data in a way which both sides think the long-term key of either side is the same. This is due to a lack of validation that the ephemeral or long-term keys are not of low-order.
