{"id":"CVE-2020-36458","aliases":["RUSTSEC-2020-0138"],"url":"https://o3.security/vulnerability/CVE-2020-36458","summary":"Data races in lexer","details":"lexer is a plugin based lexical reader.Affected versions of this crate implements Sync for ReaderResult<T, E> with the trait bound T: Send, E: Send. Since matching on the public enum ReaderResult<T, E> provides access to &T & &E, allowing data race to a non-Sync type T or E. This can result in a memory corruption when multiple threads concurrently access &T or &E. Suggested fix for the bug is change the trait bounds imposed on T & E to be T: Sync, E: Sync.","published":"2021-08-25T20:58:09Z","modified":"2023-11-08T04:03:46.074313Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"crates.io","name":"lexer","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36458"},{"type":"PACKAGE","url":"https://gitlab.com/nathanfaucett/rs-lexer"},{"type":"WEB","url":"https://gitlab.com/nathanfaucett/rs-lexer/-/issues/2"},{"type":"WEB","url":"https://raw.githubusercontent.com/rustsec/advisory-db/main/crates/lexer/RUSTSEC-2020-0138.md"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0138.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-11-08T04:03:46.074313Z"}}
