Prior to version 0.36.0, there is a possible consensus split given maliciously-crafted `AttesterSlashing` or `ProposerSlashing` being included on-chain. Because the developers represent `uint64` values as native javascript `number`s, there is an issue when those variables with large (greater than 2^53) `uint64` values are included on chain. In those cases, Lodestar may view valid_`AttesterSlashing` or `ProposerSlashing` as invalid, due to rounding errors in large `number` values. This causes a consensus split, where Lodestar nodes are forked away from the main network. Similarly, Lodestar may consider invalid `ProposerSlashing` as valid, thus including in proposed blocks that will be considered invalid by the network. Version 0.36.0 contains a fix for this issue. As a workaround, use `BigInt` to represent `Slot` and `Epoch` values in `AttesterSlashing` and `ProposerSlashing` objects. `BigInt` is too slow to be used in all `Slot` and `Epoch` cases, so one may carefully use `BigInt` just where necessary for consensus." } ], "metrics": [ { "cvssV3_1": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityImpact": "NONE", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N", "version": "3.1" } } ], "problemTypes": [ { "descriptions": [ { "cweId": "CWE-190", "description": "CWE-190: Integer Overflow or Wraparound", "lang": "en", "type": "CWE" } ] } ], "providerMetadata": { "dateUpdated": "2022-05-24T14:15:14", "orgId": "a0819718-46f1-4df5-94e2-005712e83aaa", "shortName": "GitHub_M" }, "references": [ { "tags": [ "x_refsource_CONFIRM" ], "url": "https://github.com/ChainSafe/lodestar/security/advisories/GHSA-cvj7-5f3c-9vg9" }, { "tags": [ "x_refsource_MISC" ], "url": "https://github.com/ChainSafe/lodestar/pull/3977" }, { "tags": [ "x_refsource_MISC" ], "url": "https://github.com/ChainSafe/lodestar/releases/tag/v0.36.0" } ], "source": { "advisory": "GHSA-cvj7-5f3c-9vg9", "discovery": "UNKNOWN" }, "title": "Integer Overflow in Lodestar", "x_legacyV4Record": { "CVE_data_meta": { "ASSIGNER": "security-advisories@github.com", "ID": "CVE-2022-29219", "STATE": "PUBLIC", "TITLE": "Integer Overflow in Lodestar" }, "affects": { "vendor": { "vendor_data": [ { "product": { "product_data": [ { "product_name": "lodestar", "version": { "version_data": [ { "version_value": "< 0.36.0" } ] } } ] }, "vendor_name": "ChainSafe" } ] } }, "data_format": "MITRE", "data_type": "CVE", "data_version": "4.0", "description": { "description_data": [ { "lang": "eng", "value": "Lodestar is a TypeScript implementation of the Ethereum Consensus specification.
