In affected versions of the crate, the provided function yielding values\nhad no `Send` bounds despite the `Generator` itself implementing `Send`.\n\nThe generator function lacking a `Send` bound means that types that are\ndangerous to send across threads such as `Rc` could be sent as part of a\ngenerator, potentially leading to data races.\n\nThis flaw was fixed in commit [`f7d120a3b`](https://github.com/Xudong-Huang/generator-rs/commit/f7d120a3b724d06a7b623d0a4306acf8f78cb4f0)\nby enforcing that the generator function be bound by `Send`.","published":"2021-08-08T06:15:08.340Z","modified":"2026-03-14T10:29:53.193527Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"crates.io","name":"generator","fixedVersion":"0.7.0"}],"fix":{"url":"https://github.com/Xudong-Huang/generator-rs/commit/f7d120a3b724d06a7b623d0a4306acf8f78cb4f0","label":"Xudong-Huang/generator-rs@f7d120a"},"references":[{"type":"ADVISORY","url":"https://raw.githubusercontent.com/rustsec/advisory-db/main/crates/generator/RUSTSEC-2020-0151.md"},{"type":"FIX","url":"https://rustsec.org/advisories/RUSTSEC-2020-0151.html"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36471"},{"type":"WEB","url":"https://github.com/Xudong-Huang/generator-rs/issues/27"},{"type":"WEB","url":"https://github.com/Xudong-Huang/generator-rs/commit/f7d120a3b724d06a7b623d0a4306acf8f78cb4f0"},{"type":"PACKAGE","url":"https://github.com/Xudong-Huang/generator-rs"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-03-14T10:29:53.193527Z"}}
