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-m2xr-2vj4-wh94/ (Markdown: https://insights.sbomify.com/GHSA-m2xr-2vj4-wh94/index.md)","id":"GHSA-m2xr-2vj4-wh94","markdown":"https://insights.sbomify.com/GHSA-m2xr-2vj4-wh94/index.md","name":"GHSA-m2xr-2vj4-wh94","record":{"aliases":["RUSTSEC-2025-0031"],"analysis":{"component_type":"library","fix_type":"end_of_life","impacts":["code_execution","denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"Rust chess engine library","requires_auth":"none","summary":"Unsound public APIs in the unmaintained tanton_engine crate allow memory corruption, potentially leading to code execution or crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The following functions in the `tanton_engine` crate are unsound due to lack of sufficient boundary\nchecks in public API:\n\n- `Stack::offset()`\n- `ThreadStack::get()`\n- `RootMoveList::insert_score_depth()`\n- `RootMoveList::insert_score()`\n\nThe tanton_engine crate is no longer maintained, so there are no plans to fix this issue.","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"tanton_engine has unsound public API","id":"GHSA-m2xr-2vj4-wh94","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":[],"introduced":["0"],"last_affected":["1.0.0"],"package":"tanton_engine","purl":null,"source":"GHSA-m2xr-2vj4-wh94"},{"ecosystem":"crates.io","fixed":[],"introduced":["0"],"last_affected":["1.0.0"],"package":"tanton_engine","purl":"pkg:cargo/tanton_engine","source":"GHSA-m2xr-2vj4-wh94"},{"ecosystem":"crates.io","fixed":[],"introduced":["0.0.0-0"],"last_affected":[],"package":"tanton_engine","purl":"pkg:cargo/tanton_engine","source":"RUSTSEC-2025-0031"}],"products":null,"published":"2025-04-24","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Unsound public APIs in the unmaintained tanton_engine crate allow memory corruption, potentially leading to code execution or crashes.","url":"https://insights.sbomify.com/GHSA-m2xr-2vj4-wh94/"}
