{"id":"CVE-2020-36445","aliases":["RUSTSEC-2020-0125"],"url":"https://o3.security/vulnerability/CVE-2020-36445","summary":"Data races in convec","details":"Affected versions of this crate unconditionally implement Send/Sync for `ConVec<T>`.\nThis allows users to insert `T` that is not Send or not Sync.\n\nThis allows users to create data races by using non-Send types like `Arc<Cell<_>>` or `Rc<_>` as `T` in `ConVec<T>`. It is also possible to create data races by using types like `Cell<_>` or `RefCell<_>` as `T` (types that are `Send` but not `Sync`).\nSuch data races can lead to memory corruption.","published":"2021-08-25T20:59:15Z","modified":"2023-11-08T04:03:45.276409Z","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":null,"affectedPackages":[{"ecosystem":"crates.io","name":"convec","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36445"},{"type":"PACKAGE","url":"https://github.com/krl/convec"},{"type":"WEB","url":"https://raw.githubusercontent.com/rustsec/advisory-db/main/crates/convec/RUSTSEC-2020-0125.md"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0125.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T04:03:45.276409Z"}}
