It is possible to create a data race to a `T: !Sync` by invoking the `Bunch::get()` API (which returns `&T`) from multiple threads. It is also possible to send `T: !Send` to other threads by inserting `T` inside `Bunch<T>` and sending `Bunch<T>` to another thread, allowing to create a data race by inserting types like `T = Rc<_>`.\n\nSuch data races can lead to memory corruption.","affected":[{"package":{"name":"bunch","ecosystem":"crates.io","purl":"pkg:cargo/bunch"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"}]}],"ecosystem_specific":{"affected_functions":null,"affects":{"arch":[],"functions":[],"os":[]}},"database_specific":{"categories":["memory-corruption","thread-safety"],"cvss":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","informational":null,"source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2020-0130.json"}}],"references":[{"type":"PACKAGE","url":"https://crates.io/crates/bunch"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2020-0130.html"},{"type":"REPORT","url":"https://github.com/krl/bunch/issues/1"}],"database_specific":{"license":"CC0-1.0"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]} |
