Description

An issue was discovered in IBC-Go's deserialization of acknowledgements that results in non-deterministic behavior which can halt a chain. Any user that can open an IBC channel can introduce this state to the chain.

This an upstream dependency used in cheqd-node, rather than a custom module.

Impact

Could result in a chain halt.

Patches

Validators, full nodes, and IBC relayers should upgrade to cheqd-node v3.1.7. This upgrade does not require a software upgrade proposal on-chain and is meant to be non state-breaking.
