Versions prior to 0.28.0 contain a potential attack via Improper Verification of Cryptographic Signature, affecting anyone using the tendermint-light-client and related packages to perform light client verification (e.g. IBC-rs, Hermes). The light client does not check that the chain IDs of the trusted and untrusted headers match, resulting in a possible attack vector where someone who finds a header from an untrusted chain that satisfies all other verification conditions (e.g. enough overlapping validator signatures) could fool a light client. The attack vector is currently theoretical, and no proof-of-concept exists yet to exploit it on live networks. This issue is patched in version 0.28.0. There are no workarounds."}], "lastModified": "2022-12-20T16:14:56.350", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:tendermint-light-client-js_project:tendermint-light-client-js:*:*:*:*:rust:*:*:*", "vulnerable": true, "matchCriteriaId": "8AE9A733-0849-4587-8F47-A03E662F71B2", "versionEndExcluding": "0.28.0"}, {"criteria": "cpe:2.3:a:tendermint-light-client-verifier_project:tendermint-light-client-verifier:*:*:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "6722E7A5-A823-40C0-87A7-C13CABAD9466", "versionEndExcluding": "0.28.0"}, {"criteria": "cpe:2.3:a:tendermint-light-client_project:tendermint-light-client:*:*:*:*:rust:*:*:*", "vulnerable": true, "matchCriteriaId": "0DF43910-4B14-414A-A96D-947A5D4EC035", "versionEndExcluding": "0.28.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
