Summary

ASA-2024-0012

Name: ASA-2024-0012, Transaction decoding may result in a stack overflow Component: Cosmos SDK Criticality: High (Considerable Impact, and Possible Likelihood per ACMv1.2) Affected versions: cosmos-sdk versions <= v0.50.10, <= v0.47.14 Affected users: Chain Builders + Maintainers, Validators, node operators

ASA-2024-0013

Name: ASA-2024-0013: CosmosSDK: Transaction decoding may result in resource exhaustion
Component: Cosmos SDK Criticality: High (Considerable Impact, and Possible Likelihood per ACMv1.2) Affected versions: cosmos-sdk versions <= v0.50.10, <= v0.47.14 Affected users: Chain Builders + Maintainers, Validators, node operators

Impact

ASA-2024-0012

When decoding a maliciously formed packet with a deeply-nested structure, it may be possible for a stack overflow to occur and result in a network halt. This was addressed by adding a recursion limit while decoding the packet.

ASA-2024-0013

Nested messages in a transaction can consume exponential cpu and memory on UnpackAny calls. Themax_tx_bytes sets a limit for external TX but is not applied for internal messages emitted by wasm contracts or a malicious validator block. This may result in a node crashing due to resource exhaustion. This was addressed by adding additional validation to prevent this condition.

Patches

The issues above are resolved in Cosmos SDK versions v0.47.15 or v0.50.11. Please upgrade ASAP.
