{"id":"GHSA-vh7m-p724-62c2","summary":"Signature Malleabillity in elliptic","details":"The Elliptic package before version 6.5.3 for Node.js allows ECDSA signature malleability via variations in encoding, leading '\\0' bytes, or integer overflows. This could conceivably have a security-relevant impact if an application relied on a single canonical signature.","aliases":["CVE-2020-13822"],"modified":"2024-10-16T17:02:45Z","published":"2020-07-29T20:40:35Z","database_specific":{"nvd_published_at":"2020-06-04T15:15:13Z","cwe_ids":["CWE-190"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2020-07-29T20:39:31Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-13822"},{"type":"WEB","url":"https://github.com/indutny/elliptic/issues/226"},{"type":"WEB","url":"https://github.com/indutny/elliptic/commit/856fe4d99fe7b6200556e6400b3bf585b1721bec"},{"type":"PACKAGE","url":"https://github.com/indutny/elliptic"},{"type":"WEB","url":"https://medium.com/%40herman_10687/malleability-attack-why-it-matters-7b5f59fb99a4"},{"type":"WEB","url":"https://medium.com/@herman_10687/malleability-attack-why-it-matters-7b5f59fb99a4"},{"type":"WEB","url":"https://www.npmjs.com/package/elliptic"},{"type":"WEB","url":"https://yondon.blog/2019/01/01/how-not-to-use-ecdsa"}],"affected":[{"package":{"name":"elliptic","ecosystem":"npm","purl":"pkg:npm/elliptic"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"6.5.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/07/GHSA-vh7m-p724-62c2/GHSA-vh7m-p724-62c2.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:L"}]}
