{"id":"GHSA-w59h-378f-2frm","summary":"Unsound sending of non-Send types across threads in threadalone","details":"Affected versions can run the `Drop` impl of a non-Send type on a different\nthread than it was created on.\n\nThe flaw occurs when a stderr write performed by the `threadalone` crate fails,\nfor example because stderr is redirected to a location on a filesystem that is\nfull, or because stderr is a pipe that has been closed by the reader.\n\nDropping a non-Send type on the wrong thread is unsound. If used with a type\nsuch as a pthread-based `MutexGuard`, [the consequence is undefined\nbehavior][mutexguard]. If used with `Rc`, there would be a data race on the\nreference count, which is likewise undefined behavior.\n\n[mutexguard]: https://github.com/rust-lang/rust/issues/23465#issuecomment-82730326\n\n","aliases":["RUSTSEC-2024-0005"],"modified":"2024-02-10T16:26:49.036729Z","published":"2024-01-23T14:43:35Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2024-01-23T14:43:35Z","nvd_published_at":null,"cwe_ids":[]},"references":[{"type":"WEB","url":"https://github.com/cr0sh/threadalone/issues/1"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2024-0005.html"}],"affected":[{"package":{"name":"threadalone","ecosystem":"crates.io","purl":"pkg:cargo/threadalone"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.2.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-w59h-378f-2frm/GHSA-w59h-378f-2frm.json"}}],"schema_version":"1.9.0"}
