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 …
ASA-2024-006: ValidateVoteExtensions helper function may allow incorrect voting power assumptions Component: Cosmos SDK Criticality: High Affected Versions: Cosmos SDK versions <= 0.50.4, on 0.50 branches Affected Users: Chain developers, Validator and Node operators Impact: Elevation of Privilege Summary The default ValidateVoteExtensions helper function infers total voting power based off of the injected VoteExtension, which are injected by the proposer. If your chain utilizes the ValidateVoteExtensions helper in ProcessProposal, a dishonest …
An issue was identified in the slashing mechanism that may allow for the evasion of slashing penalties during a slashing event. If a delegation contributed to byzantine behavior of a validator, and the validator has not yet been slashed, it may be possible for that delegation to evade a pending slashing penalty through re-delegation behavior. Additional validation logic was added to restrict this behavior.
ASA-2024-003: Missing BlockedAddressed Validation in Vesting Module Component: Cosmos SDK Criticality: Low Affected Versions: Cosmos SDK versions <= 0.50.3; <= 0.47.8 Affected Users: Chain developers, Validator and Node operators Impact: Denial of Service Description A vulnerability was identified in the x/auth/vesting module, which can allow a user to create a periodic vesting account on a blocked address, for example a non-initialized module account. Additional validation was added to prevent creation …
