{"id":"GHSA-rw2c-c256-3r53","summary":"Data races in hashconsing","details":"Affected versions of hashconsing implements Send/Sync for its HConsed type without restricting it to Sendable types and Syncable types. This allows non-Sync types such as Cell to be shared across threads leading to undefined behavior and memory corruption in concurrent programs.","aliases":["CVE-2020-36215","RUSTSEC-2020-0107"],"modified":"2023-11-08T04:03:41.965428Z","published":"2021-08-25T20:51:52Z","database_specific":{"cwe_ids":["CWE-662","CWE-787"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-08-19T18:47:26Z","nvd_published_at":"2021-01-26T18:15:00Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36215"},{"type":"WEB","url":"https://github.com/AdrienChampion/hashconsing/issues/1"},{"type":"PACKAGE","url":"https://github.com/AdrienChampion/hashconsing"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0107.html"}],"affected":[{"package":{"name":"hashconsing","ecosystem":"crates.io","purl":"pkg:cargo/hashconsing"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.1.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-rw2c-c256-3r53/GHSA-rw2c-c256-3r53.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
