{"id":"GHSA-9j8q-m9x5-9g6j","summary":"Data races in async-coap","details":"An issue was discovered in the async-coap crate through 2020-12-08 for Rust. \nAffected versions of this crate implement Send/Sync for `ArcGuard\u003cRC, T\u003e` with no trait bounds on `RC`. This allows users to send `RC: !Send` to other threads and also allows users to concurrently access `Rc: !Sync` from multiple threads.\n\nThis can result in memory corruption from data race or other undefined behavior caused by sending `T: !Send` to other threads (e.g. dropping `MutexGuard\u003cT\u003e` in another thread that didn't lock its mutex).\n","aliases":["CVE-2020-36444","RUSTSEC-2020-0124"],"modified":"2023-11-08T04:03:45.205946Z","published":"2021-08-25T20:59:11Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-08-09T21:45:44Z","nvd_published_at":"2021-08-08T06:15:00Z","cwe_ids":["CWE-119","CWE-362"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36444"},{"type":"WEB","url":"https://github.com/google/rust-async-coap/issues/33"},{"type":"PACKAGE","url":"https://github.com/google/rust-async-coap"},{"type":"WEB","url":"https://raw.githubusercontent.com/rustsec/advisory-db/main/crates/async-coap/RUSTSEC-2020-0124.md"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0124.html"}],"affected":[{"package":{"name":"async-coap","ecosystem":"crates.io","purl":"pkg:cargo/async-coap"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"0.1.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-9j8q-m9x5-9g6j/GHSA-9j8q-m9x5-9g6j.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
