{"id":"GHSA-fvhr-7j8m-3cvc","summary":"Data races in appendix","details":"The `appendix` crate implements a key-value mapping data structure called\n`Index\u003cK, V\u003e` that is stored on disk. The crate allows for any type to inhabit\nthe generic `K` and `V` type parameters and implements Send and Sync for them\nunconditionally.\n\nUsing a type that is not marked as `Send` or `Sync` with `Index` can allow it\nto be used across multiple threads leading to data races. Additionally using\nreference types for the keys or values will lead to the segmentation faults\nin the crate's code.","aliases":["CVE-2020-36469","RUSTSEC-2020-0149"],"modified":"2023-11-08T04:03:46.748675Z","published":"2021-08-25T20:57:02Z","database_specific":{"nvd_published_at":"2021-08-08T06:15:00Z","cwe_ids":["CWE-362"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2021-08-18T20:35:37Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36469"},{"type":"WEB","url":"https://github.com/krl/appendix/issues/6"},{"type":"PACKAGE","url":"https://github.com/krl/appendix"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0149.html"}],"affected":[{"package":{"name":"appendix","ecosystem":"crates.io","purl":"pkg:cargo/appendix"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"0.2.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-fvhr-7j8m-3cvc/GHSA-fvhr-7j8m-3cvc.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
