{"id":"GHSA-64j8-7gp2-xjx5","summary":"Data races in try-mutex","details":"Affected versions of this crate unconditionally implemented Sync trait for TryMutex\u003cT\u003e type. This allows users to put non-Send T type in TryMutex and send it to another thread, which can cause a data race. The flaw was corrected in the 0.3.0 release by adding T: Send bound for the Sync trait implementation.","aliases":["CVE-2020-35924","RUSTSEC-2020-0087"],"modified":"2023-11-08T04:03:39.649741Z","published":"2021-08-25T20:50:28Z","database_specific":{"cwe_ids":["CWE-787"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2021-08-19T18:54:53Z","nvd_published_at":null},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-35924"},{"type":"WEB","url":"https://github.com/mpdn/try-mutex/issues/2"},{"type":"PACKAGE","url":"https://github.com/mpdn/try-mutex"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0087.html"}],"affected":[{"package":{"name":"try-mutex","ecosystem":"crates.io","purl":"pkg:cargo/try-mutex"},"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-64j8-7gp2-xjx5/GHSA-64j8-7gp2-xjx5.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
