{"id":"RUSTSEC-2020-0116","summary":"PinSlab\u003cT\u003e and Unordered\u003cT, S\u003e need bounds on their Send/Sync traits","details":"Affected versions of this crate unconditionally implemented `Send` & `Sync` for types `PinSlab\u003cT\u003e` & `Unordered\u003cT, S\u003e`. 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\u003cT\u003e` or `Unordered\u003cT, S\u003e` 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\u003cT\u003e` & `Unordered\u003cT, S\u003e` and adding `T: Sync` to `Sync` impls for `PinSlab\u003cT\u003e` & `Unordered\u003cT, S\u003e`.","aliases":["CVE-2020-36436","GHSA-686f-ch3r-xwmh"],"modified":"2023-11-08T04:03:44.721625Z","published":"2020-11-15T12:00:00Z","database_specific":{"license":"CC0-1.0"},"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"}],"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":[],"os":[],"functions":[]}},"database_specific":{"informational":null,"categories":["memory-corruption","thread-safety"],"source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2020-0116.json","cvss":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
