Affected packages
• Go github.com/cheqd/cheqd-node: < 3.1.7 → fixed in 3.1.7
Description
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.
