{"id":"GHSA-xwxc-j97j-84gf","summary":"Race condition in Parc","details":"In the affected versions of this crate, `LockWeak\u003cT\u003e` unconditionally implemented `Send` with no trait bounds on `T`. `LockWeak\u003cT\u003e` doesn't own `T` and only provides `&T`. This allows concurrent access to a non-Sync `T`, which can cause undefined behavior like data races.\n","aliases":["CVE-2020-36454","GHSA-29v7-3v4c-gf38","RUSTSEC-2020-0134"],"modified":"2023-11-08T04:03:45.827550Z","published":"2021-08-25T21:00:03Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2021-08-09T17:05:10Z","nvd_published_at":null,"cwe_ids":["CWE-362"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/hyyking/rustracts/pull/6"},{"type":"PACKAGE","url":"https://github.com/hyyking/rustracts/tree/master/parc"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0134.html"}],"affected":[{"package":{"name":"parc","ecosystem":"crates.io","purl":"pkg:cargo/parc"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"1.0.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-xwxc-j97j-84gf/GHSA-xwxc-j97j-84gf.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"}]}
