{"id":"GHSA-3837-87vh-xq3w","summary":"Data race 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\nSyncRef\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.","aliases":["CVE-2020-36447","GHSA-pfjq-935c-4895","RUSTSEC-2020-0127"],"modified":"2023-11-08T04:03:45.399019Z","published":"2021-08-25T20:57:07Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-08-18T20:31:57Z","cwe_ids":["CWE-77"],"nvd_published_at":"2021-08-08T06:15:00Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36447"},{"type":"WEB","url":"https://github.com/purpleposeidon/v9/issues/1"},{"type":"WEB","url":"https://github.com/purpleposeidon/v9/commit/18847c50e5d36561cc91c996c3539ddb1eacf6c7"},{"type":"PACKAGE","url":"https://github.com/purpleposeidon/v9"},{"type":"WEB","url":"https://raw.githubusercontent.com/rustsec/advisory-db/main/crates/v9/RUSTSEC-2020-0127.md"},{"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-3837-87vh-xq3w/GHSA-3837-87vh-xq3w.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
