{"id":"GHSA-77m6-x95j-75r5","summary":"Data races in ticketed_lock","details":"Affected versions of this crate unconditionally implemented Send for ReadTicket\u003cT\u003e & WriteTicket\u003cT\u003e. This allows to send non-Send T to other threads. This can allows creating data races by cloning types with internal mutability and sending them to other threads (as T of ReadTicket\u003cT\u003e/WriteTicket\u003cT\u003e). Such data races can cause memory corruption or other undefined behavior. The flaw was corrected in commit `a986a93` by adding T: Send bounds to Send impls of ReadTicket\u003cT\u003e/WriteTicket\u003cT\u003e.","aliases":["CVE-2020-36439","GHSA-gq4h-f254-7cw9","RUSTSEC-2020-0119"],"modified":"2023-11-08T04:03:44.903828Z","published":"2021-08-25T20:58:58Z","database_specific":{"nvd_published_at":"2021-08-08T06:15:00Z","cwe_ids":["CWE-119","CWE-362"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-08-09T22:40:34Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36439"},{"type":"WEB","url":"https://github.com/kvark/ticketed_lock/issues/7"},{"type":"WEB","url":"https://github.com/kvark/ticketed_lock/commit/a986a9335d591fa5c826157d1674d47aa525357f"},{"type":"WEB","url":"https://github.com/kvark/ticketed_lock"},{"type":"WEB","url":"https://raw.githubusercontent.com/rustsec/advisory-db/main/crates/ticketed_lock/RUSTSEC-2020-0119.md"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0119.html"}],"affected":[{"package":{"name":"ticketed_lock","ecosystem":"crates.io","purl":"pkg:cargo/ticketed_lock"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.3.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-77m6-x95j-75r5/GHSA-77m6-x95j-75r5.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"}]}
