{"id":"UBUNTU-CVE-2020-28498","details":"The package elliptic before 6.5.4 are vulnerable to Cryptographic Issues via the secp256k1 implementation in elliptic/ec/key.js. There is no check to confirm that the public key point passed into the derive function actually exists on the secp256k1 curve. This results in the potential for the private key used in this implementation to be revealed after a number of ECDH operations are performed.","modified":"2026-05-20T16:04:24.061423835Z","published":"2021-02-02T19:15:00Z","upstream":["CVE-2020-28498"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-28498"},{"type":"REPORT","url":"https://github.com/christianlundkvist/blog/blob/master/2020_05_26_secp256k1_twist_attacks/secp256k1_twist_attacks.md"},{"type":"REPORT","url":"https://github.com/indutny/elliptic/commit/441b7428b0e8f6636c42118ad2aaa186d3c34c3f"},{"type":"REPORT","url":"https://snyk.io/vuln/SNYK-JAVA-ORGWEBJARSNPM-1069836"},{"type":"REPORT","url":"https://snyk.io/vuln/SNYK-JS-ELLIPTIC-1064899"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-28498"}],"affected":[{"package":{"name":"node-elliptic","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/node-elliptic?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.4.0+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-elliptic","binary_version":"6.4.0+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-28498.json"}},{"package":{"name":"node-elliptic","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-elliptic?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.5.1~dfsg-1","6.5.1~dfsg-2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-elliptic","binary_version":"6.5.1~dfsg-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-28498.json"}},{"package":{"name":"node-elliptic","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-elliptic?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.5.4~dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"6.5.4~dfsg-1","binary_name":"node-elliptic"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-28498.json"}},{"package":{"name":"node-elliptic","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/node-elliptic?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.5.4~dfsg-2"],"ecosystem_specific":{"binaries":[{"binary_version":"6.5.4~dfsg-2","binary_name":"node-elliptic"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-28498.json"}},{"package":{"name":"node-elliptic","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/node-elliptic?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.6.1+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"node-elliptic","binary_version":"6.6.1+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-28498.json"}},{"package":{"name":"node-elliptic","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/node-elliptic?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.6.1+dfsg-1","6.6.1+dfsg+~6.4.18-1"],"ecosystem_specific":{"binaries":[{"binary_version":"6.6.1+dfsg+~6.4.18-1","binary_name":"node-elliptic"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-28498.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
