{"id":"RUSTSEC-2024-0005","summary":"Unsound sending of non-Send types across threads","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","aliases":["GHSA-w59h-378f-2frm"],"modified":"2024-02-10T16:26:49.036729Z","published":"2024-01-07T12:00:00Z","database_specific":{"license":"CC0-1.0"},"references":[{"type":"PACKAGE","url":"https://crates.io/crates/threadalone"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2024-0005.html"},{"type":"REPORT","url":"https://github.com/cr0sh/threadalone/issues/1"}],"affected":[{"package":{"name":"threadalone","ecosystem":"crates.io","purl":"pkg:cargo/threadalone"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"},{"fixed":"0.2.1"}]}],"ecosystem_specific":{"affected_functions":null,"affects":{"os":[],"arch":[],"functions":[]}},"database_specific":{"categories":[],"cvss":null,"informational":"unsound","source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2024-0005.json"}}],"schema_version":"1.7.3"}
