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-mpg5-fvwp-42m2/ (Markdown: https://insights.sbomify.com/GHSA-mpg5-fvwp-42m2/index.md)","id":"GHSA-mpg5-fvwp-42m2","markdown":"https://insights.sbomify.com/GHSA-mpg5-fvwp-42m2/index.md","name":"GHSA-mpg5-fvwp-42m2","record":{"aliases":["RUSTSEC-2022-0002"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"Rust concurrency library","requires_auth":"none","summary":"A memory safety flaw in the dashmap Rust library allows references to outlive locks, causing undefined behavior and potential application 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":"Reference returned by some methods of `Ref` (and similar types) may outlive the `Ref` and escape the lock.\nThis causes undefined behavior and may result in a segfault.\n\nMore information in [`dashmap#167`](https://github.com/xacrimon/dashmap/issues/167) 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":true,"headline":"Unsoundness in `dashmap` references","id":"GHSA-mpg5-fvwp-42m2","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["5.1.0"],"introduced":["5.0.0"],"last_affected":[],"package":"dashmap","purl":null,"source":"GHSA-mpg5-fvwp-42m2"},{"ecosystem":"crates.io","fixed":["5.1.0"],"introduced":["5.0.0"],"last_affected":[],"package":"dashmap","purl":"pkg:cargo/dashmap","source":"GHSA-mpg5-fvwp-42m2"},{"ecosystem":"crates.io","fixed":["5.1.0"],"introduced":["5.0.0"],"last_affected":[],"package":"dashmap","purl":"pkg:cargo/dashmap","source":"RUSTSEC-2022-0002"}],"products":null,"published":"2022-01-10","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":"A memory safety flaw in the dashmap Rust library allows references to outlive locks, causing undefined behavior and potential application crashes.","url":"https://insights.sbomify.com/GHSA-mpg5-fvwp-42m2/"}
