{"id":"GHSA-pfjq-935c-4895","summary":"Data races in v9","details":"Affected versions of this crate unconditionally implement `Sync` for `SyncRef\u003cT\u003e`. This definition allows data races if `&T` is accessible through `&SyncRef`.\n\n`SyncRef\u003cT\u003e` derives `Clone` and `Debug`, and the default implementations of those traits access `&T` by invoking `T::clone()` & `T::fmt()`. It is possible to create data races & undefined behavior by concurrently invoking `SyncRef\u003cT\u003e::clone()` or `SyncRef\u003cT\u003e::fmt()` from multiple threads with `T: !Sync`.\n","aliases":["CVE-2020-36447","GHSA-3837-87vh-xq3w","RUSTSEC-2020-0127"],"modified":"2023-11-08T04:03:45.399019Z","published":"2021-08-25T21:00:37Z","database_specific":{"cwe_ids":["CWE-362"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-08-05T21:37:57Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/purpleposeidon/v9/issues/1"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0127.html"}],"affected":[{"package":{"name":"v9","ecosystem":"crates.io","purl":"pkg:cargo/v9"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.1.43"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-pfjq-935c-4895/GHSA-pfjq-935c-4895.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:H/I:H/A:H"}]}
