{"id":"GHSA-hrjm-c879-pp86","summary":"libsecp256k1 contains side-channel timing attack","details":"Versions of libsecp256k1 prior to 0.3.1 did not execute `Scalar::check_overflow` in constant time. This allows an attacker to potentially leak information via a timing attack. The flaw was corrected by modifying `Scalar::check_overflow` to execute in constant time.","aliases":["CVE-2019-25003","RUSTSEC-2019-0027"],"modified":"2023-11-08T04:01:32.045348Z","published":"2021-08-25T20:46:46Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2021-08-19T21:19:40Z","nvd_published_at":null,"cwe_ids":["CWE-208"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-25003"},{"type":"WEB","url":"https://github.com/paritytech/libsecp256k1/commit/11ba23a9766a5079918cd9f515bc100bc8164b50"},{"type":"PACKAGE","url":"https://github.com/paritytech/libsecp256k1"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2019-0027.html"}],"affected":[{"package":{"name":"libsecp256k1","ecosystem":"crates.io","purl":"pkg:cargo/libsecp256k1"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.3.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-hrjm-c879-pp86/GHSA-hrjm-c879-pp86.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
