{"id":"GHSA-vmqh-5232-v43r","summary":"Panic in wasmvm can slow down block production","details":"# CWA-2024-008\n\n**Severity**\n\nMedium (Moderate + Likely)[^1]\n\n**Affected versions:**\n\n- wasmvm \u003e= 2.1.0, \u003c 2.1.3\n- wasmvm \u003e= 2.0.0, \u003c 2.0.4\n- wasmvm \u003c 1.5.5\n- cosmwasm-vm \u003e= 2.1.0, \u003c 2.1.4\n- cosmwasm-vm \u003e= 2.0.0, \u003c 2.0.7\n- cosmwasm-vm \u003c 1.5.8\n\n**Patched versions:**\n\n- wasmvm 1.5.5, 2.0.4, 2.1.3\n- cosmwasm-vm 1.5.8, 2.0.7, 2.1.4\n\n## Description of the bug\n\n(Blank for now. We'll add more detail once chains had a chance to upgrade.)\n\n## Patch\n\n- 1.5: https://github.com/CosmWasm/cosmwasm/commit/edcdbc520d4f5521eed42de6e2869658278e91fd\n- 2.0: https://github.com/CosmWasm/cosmwasm/commit/f63429ca59eb44dd5d780c1572016581337091e4\n- 2.1: https://github.com/CosmWasm/cosmwasm/commit/108e7dcbf9c21df0fa83f355ad3a7355d7f220cb\n\n## Applying the patch\n\nThe patch will be shipped in releases of wasmvm. You can update more or less as follows:\n\n1. Check the current wasmvm version: `go list -m github.com/CosmWasm/wasmvm`\n2. Bump the `github.com/CosmWasm/wasmvm` dependency in your go.mod to 1.5.5, 2.0.4, 2.1.3 depending on which minor version you are; `go mod tidy`; commit.\n3. If you use the static libraries `libwasmvm_muslc.aarch64.a`/`libwasmvm_muslc.x86_64.a`, update them accordingly.\n4. Check the updated wasmvm version: `go list -m github.com/CosmWasm/wasmvm` and ensure you see 1.5.5, 2.0.4, 2.1.3.\n5. Follow your regular practices to deploy chain upgrades.\n\nTo double check if the correct library version is loaded at runtime, use this query:\n`\u003cappd\u003e query wasm libwasmvm-version`. It must show 1.5.5, 2.0.4 or 2.1.3.\n\nThe patch is consensus breaking and requires a coordinated upgrade.\n\n## Acknowledgement\n\nThis issue was found by meadow101 who reported it to the Cosmos Bug Bounty Program on HackerOne.\n\nIf you believe you have found a bug in the Interchain Stack or would like to contribute to the\nprogram by reporting a bug, please see \u003chttps://hackerone.com/cosmos\u003e.\n\n## Timeline\n\n- 2024-08-22: Confio receives a report through the Cosmos bug bounty program maintained by Amulet.\n- 2024-08-23: Confio security contributors confirm the report.\n- 2024-09-09: Confio developed the patch internally.\n- 2024-09-23: Patch is released.\n\n[^1]: following Amulet's Severity Classification Framework ACMv1: https://github.com/interchainio/security/blob/e0227a1fb4059144aab4f6003eeee7f09912db3a/resources/CLASSIFICATION_MATRIX.md","modified":"2024-12-10T16:55:37Z","published":"2024-12-10T16:55:37Z","database_specific":{"nvd_published_at":null,"cwe_ids":[],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2024-12-10T16:55:37Z"},"references":[{"type":"WEB","url":"https://github.com/CosmWasm/wasmvm/security/advisories/GHSA-vmqh-5232-v43r"},{"type":"WEB","url":"https://github.com/CosmWasm/cosmwasm/commit/108e7dcbf9c21df0fa83f355ad3a7355d7f220cb"},{"type":"WEB","url":"https://github.com/CosmWasm/cosmwasm/commit/edcdbc520d4f5521eed42de6e2869658278e91fd"},{"type":"WEB","url":"https://github.com/CosmWasm/cosmwasm/commit/f63429ca59eb44dd5d780c1572016581337091e4"},{"type":"WEB","url":"https://github.com/CosmWasm/advisories/blob/main/CWAs/CWA-2024-008.md"},{"type":"PACKAGE","url":"https://github.com/CosmWasm/wasmvm"}],"affected":[{"package":{"name":"github.com/CosmWasm/wasmvm/v2","ecosystem":"Go","purl":"pkg:golang/github.com/CosmWasm/wasmvm/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.1.0"},{"fixed":"2.1.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/12/GHSA-vmqh-5232-v43r/GHSA-vmqh-5232-v43r.json"}},{"package":{"name":"github.com/CosmWasm/wasmvm/v2","ecosystem":"Go","purl":"pkg:golang/github.com/CosmWasm/wasmvm/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0"},{"fixed":"2.0.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/12/GHSA-vmqh-5232-v43r/GHSA-vmqh-5232-v43r.json"}},{"package":{"name":"github.com/CosmWasm/wasmvm","ecosystem":"Go","purl":"pkg:golang/github.com/CosmWasm/wasmvm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.5.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/12/GHSA-vmqh-5232-v43r/GHSA-vmqh-5232-v43r.json"}},{"package":{"name":"cosmwasm-vm","ecosystem":"crates.io","purl":"pkg:cargo/cosmwasm-vm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.1.0"},{"fixed":"2.1.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/12/GHSA-vmqh-5232-v43r/GHSA-vmqh-5232-v43r.json"}},{"package":{"name":"cosmwasm-vm","ecosystem":"crates.io","purl":"pkg:cargo/cosmwasm-vm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0"},{"fixed":"2.0.7"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/12/GHSA-vmqh-5232-v43r/GHSA-vmqh-5232-v43r.json"}},{"package":{"name":"cosmwasm-vm","ecosystem":"crates.io","purl":"pkg:cargo/cosmwasm-vm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.5.8"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/12/GHSA-vmqh-5232-v43r/GHSA-vmqh-5232-v43r.json"}}],"schema_version":"1.9.0"}
