Leakage of a bit-length of the scalar during scalar multiplication is possible on an elliptic curve which might allow practical recovery of the long-term private key.","severity":"high","score":7.4,"published":"2019-11-20T01:34:50.000Z","modified":"2026-07-08T05:56:15.694Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"simplito/elliptic-php","sources":[{"name":"OSV · GHSA-mr6r-82x4-f4jj","url":"https://osv.dev/vulnerability/GHSA-mr6r-82x4-f4jj"}],"ranges":[{"events":[{"introduced":"0"},{"fixed":"1.0.6"}],"type":"ECOSYSTEM"}],"versions":["1.0.0","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5"],"fixed":["1.0.6"]}],"sourceAffected":[],"references":["https://nvd.nist.gov/vuln/detail/CVE-2019-10764","https://github.com/simplito/elliptic-php/commit/15652609aa55968d56685c2a9120535ccdc00fd9","https://minerva.crocs.fi.muni.cz","https://snyk.io/vuln/SNYK-PHP-SIMPLITOELLIPTICPHP-534576"],"sources":[{"name":"OSV","id":"GHSA-mr6r-82x4-f4jj","modified":"2026-07-08T05:56:15.694235354Z","url":"https://osv.dev/vulnerability/GHSA-mr6r-82x4-f4jj"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4}],"products":[],"remediation":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T22:15:33.378Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
