An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-vmqh-5232-v43r in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/CosmWasm/wasmvm/v2 (Go): affected from 2.0.0; fixed in 2.0.4\n- github.com/CosmWasm/wasmvm/v2 (Go): affected from 2.0.0; fixed in 2.0.4\n- github.com/CosmWasm/wasmvm/v2 (Go): affected from 2.1.0; fixed in 2.1.3\n- github.com/CosmWasm/wasmvm/v2 (Go): affected from 2.1.0; fixed in 2.1.3\n- github.com/CosmWasm/wasmvm (Go): affected all versions; fixed in 1.5.5\n- github.com/CosmWasm/wasmvm (Go): affected all versions; fixed in 1.5.5\n- cosmwasm-vm (crates.io): affected all versions; fixed in 1.5.8\n- cosmwasm-vm (crates.io): affected all versions; fixed in 1.5.8\n- cosmwasm-vm (crates.io): affected from 2.0.0; fixed in 2.0.7\n- cosmwasm-vm (crates.io): affected from 2.0.0; fixed in 2.0.7\n- cosmwasm-vm (crates.io): affected from 2.1.0; fixed in 2.1.4\n- cosmwasm-vm (crates.io): affected from 2.1.0; fixed in 2.1.4\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-vmqh-5232-v43r/ (Markdown: https://insights.sbomify.com/GHSA-vmqh-5232-v43r/index.md)","id":"GHSA-vmqh-5232-v43r","markdown":"https://insights.sbomify.com/GHSA-vmqh-5232-v43r/index.md","name":"GHSA-vmqh-5232-v43r","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CosmWasm VM library","requires_auth":"none","summary":"A panic in the CosmWasm VM library can slow down block production, causing a denial of service for blockchain networks using affected versions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"# 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.

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","ecosystems":["Go","crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Panic in wasmvm can slow down block production","id":"GHSA-vmqh-5232-v43r","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":12,"n_references":null,"packages":[{"ecosystem":"Go","fixed":["1.5.5"],"introduced":["0"],"last_affected":[],"package":"github.com/CosmWasm/wasmvm","purl":null,"source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"Go","fixed":["1.5.5"],"introduced":["0"],"last_affected":[],"package":"github.com/CosmWasm/wasmvm","purl":"pkg:golang/github.com/CosmWasm/wasmvm","source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"Go","fixed":["2.0.4"],"introduced":["2.0.0"],"last_affected":[],"package":"github.com/CosmWasm/wasmvm/v2","purl":null,"source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"Go","fixed":["2.0.4"],"introduced":["2.0.0"],"last_affected":[],"package":"github.com/CosmWasm/wasmvm/v2","purl":"pkg:golang/github.com/CosmWasm/wasmvm/v2","source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"Go","fixed":["2.1.3"],"introduced":["2.1.0"],"last_affected":[],"package":"github.com/CosmWasm/wasmvm/v2","purl":null,"source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"Go","fixed":["2.1.3"],"introduced":["2.1.0"],"last_affected":[],"package":"github.com/CosmWasm/wasmvm/v2","purl":"pkg:golang/github.com/CosmWasm/wasmvm/v2","source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"crates.io","fixed":["1.5.8"],"introduced":["0"],"last_affected":[],"package":"cosmwasm-vm","purl":null,"source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"crates.io","fixed":["1.5.8"],"introduced":["0"],"last_affected":[],"package":"cosmwasm-vm","purl":"pkg:cargo/cosmwasm-vm","source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"crates.io","fixed":["2.0.7"],"introduced":["2.0.0"],"last_affected":[],"package":"cosmwasm-vm","purl":null,"source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"crates.io","fixed":["2.0.7"],"introduced":["2.0.0"],"last_affected":[],"package":"cosmwasm-vm","purl":"pkg:cargo/cosmwasm-vm","source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"crates.io","fixed":["2.1.4"],"introduced":["2.1.0"],"last_affected":[],"package":"cosmwasm-vm","purl":null,"source":"GHSA-vmqh-5232-v43r"},{"ecosystem":"crates.io","fixed":["2.1.4"],"introduced":["2.1.0"],"last_affected":[],"package":"cosmwasm-vm","purl":"pkg:cargo/cosmwasm-vm","source":"GHSA-vmqh-5232-v43r"}],"products":null,"published":"2024-12-10","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"A panic in the CosmWasm VM library can slow down block production, causing a denial of service for blockchain networks using affected versions.","url":"https://insights.sbomify.com/GHSA-vmqh-5232-v43r/"}
