{"id":"CVE-2020-36439","aliases":["GHSA-gq4h-f254-7cw9","RUSTSEC-2020-0119"],"url":"https://o3.security/vulnerability/CVE-2020-36439","summary":"Data races in ticketed_lock","details":"Affected versions of this crate unconditionally implemented Send for ReadTicket<T> & WriteTicket<T>. 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<T>/WriteTicket<T>). 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<T>/WriteTicket<T>.","published":"2021-08-25T20:58:58Z","modified":"2023-11-08T04:03:44.903828Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"ticketed_lock","fixedVersion":"0.3.0"}],"fix":{"url":"https://github.com/kvark/ticketed_lock/commit/a986a9335d591fa5c826157d1674d47aa525357f","label":"kvark/ticketed_lock@a986a93"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T04:03:44.903828Z"}}
