However, since the guard is supposed to represent\nan **acquired lock** and allows concurrent access to the underlying data from\ndifferent threads, it should only be `Sync` when the underlying data is.\n\nThis is a soundness issue and allows data races, potentially leading to crashes\nand segfaults from safe Rust code.\n\nThe flaw was corrected by adding a `T: Send + Sync` bound for\n`GenericMutexGuard`'s `Sync` trait.\n\nThis bug is [similar to one](https://github.com/rust-lang/rust/issues/41622) in\n`std::sync::Mutex`.","affected":[{"package":{"name":"futures-intrusive","ecosystem":"crates.io","purl":"pkg:cargo/futures-intrusive"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"},{"fixed":"0.4.0"}]}],"ecosystem_specific":{"affected_functions":null,"affects":{"arch":[],"functions":[],"os":[]}},"database_specific":{"categories":["memory-corruption","thread-safety"],"cvss":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","informational":"unsound","source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2020-0072.json"}}],"references":[{"type":"PACKAGE","url":"https://crates.io/crates/futures-intrusive"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2020-0072.html"},{"type":"REPORT","url":"https://github.com/Matthias247/futures-intrusive/issues/53"}],"database_specific":{"license":"CC0-1.0"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]} |
