{"id":"RUSTSEC-2020-0151","summary":"Generators can cause data races if non-Send types are used in their generator functions","details":"The `Generator` type is an iterable which uses a generator function that yields\nvalues. 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`.","aliases":["CVE-2020-36471","GHSA-w3g5-2848-2v8r"],"modified":"2023-11-08T04:03:46.869250Z","published":"2020-11-16T12:00:00Z","database_specific":{"license":"CC0-1.0"},"references":[{"type":"PACKAGE","url":"https://crates.io/crates/generator"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2020-0151.html"},{"type":"REPORT","url":"https://github.com/Xudong-Huang/generator-rs/issues/27"}],"affected":[{"package":{"name":"generator","ecosystem":"crates.io","purl":"pkg:cargo/generator"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"},{"fixed":"0.7.0"}]}],"ecosystem_specific":{"affected_functions":null,"affects":{"arch":[],"functions":[],"os":[]}},"database_specific":{"categories":["memory-corruption"],"cvss":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","informational":null,"source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2020-0151.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
