The new user will get a reference to freed memory.\n\nThis was fixed by serializing access to an interned object while it is being deallocated.\n\nVersions prior to 0.3.12 used stronger locking which avoided the problem.","published":"2021-08-25T20:46:51Z","modified":"2023-11-08T04:03:36.887095Z","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":1,"affectedPackages":[{"ecosystem":"crates.io","name":"internment","fixedVersion":"0.4.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-35874"},{"type":"WEB","url":"https://github.com/droundy/internment/issues/11"},{"type":"PACKAGE","url":"https://github.com/droundy/internment"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0017.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T04:03:36.887095Z"}}
