In\norder to satisfy the requirement that `static` items must implement `Sync`,\n`Singleton` implemented both `Sync` and `Send` unconditionally.\n\nThis allows for a bug where non-`Sync` types such as `Cell` can be used in\nsingletons and cause data races in concurrent programs.\n\nThe flaw was corrected in commit `b0d2bd20e` by adding trait bounds, requiring\nthe contaiend type to implement `Sync`.\n","published":"2021-08-25T20:58:19Z","modified":"2023-11-08T04:03:44.661151Z","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":"ruspiro-singleton","fixedVersion":"0.4.1"}],"fix":{"url":"https://github.com/RusPiRo/ruspiro-singleton/pull/11","label":"RusPiRo/ruspiro-singleton#11"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36435"},{"type":"WEB","url":"https://github.com/RusPiRo/ruspiro-singleton/issues/10"},{"type":"WEB","url":"https://github.com/RusPiRo/ruspiro-singleton/pull/11"},{"type":"WEB","url":"https://github.com/RusPiRo/ruspiro-singleton/commit/b0d2bd20eb40b9cbc2958b981ba2dcd9e6f9396e"},{"type":"PACKAGE","url":"https://github.com/RusPiRo/ruspiro-singleton"},{"type":"WEB","url":"https://raw.githubusercontent.com/rustsec/advisory-db/main/crates/ruspiro-singleton/RUSTSEC-2020-0115.md"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0115.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T04:03:44.661151Z"}}
