This allows sending non-Send types to other threads and concurrently accessing non-Sync types from multiple threads.\n\nThis can result in a data race & memory corruption when types that provide internal mutability without synchronization are contained within `PinSlab<T>` or `Unordered<T, S>` and accessed concurrently from multiple threads.\n\nThe flaw was corrected in commits 92f40b4 & 6a6c367 by adding trait bound `T: Send` to `Send` impls for `PinSlab<T>` & `Unordered<T, S>` and adding `T: Sync` to `Sync` impls for `PinSlab<T>` & `Unordered<T, S>`.","affected":[{"package":{"name":"unicycle","ecosystem":"crates.io","purl":"pkg:cargo/unicycle"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"},{"fixed":"0.7.1"}]}],"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-2020-0116.json"}}],"references":[{"type":"PACKAGE","url":"https://crates.io/crates/unicycle"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2020-0116.html"},{"type":"REPORT","url":"https://github.com/udoprog/unicycle/issues/8"}],"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"}]} |
