An attacker capable of precisely measuring the time taken for ECC key generation may be able to derive information about the high bits of the secret key, as the function to derive the public point from the secret scalar uses an unblinded Montgomery ladder whose loop iteration count depends on the bitlength of the secret. This issue affects only key generation, not ECDSA signatures or ECDH key agreement.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2018-20187","reference_id":"","reference_type":"","scores":[{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65507","published_at":"2026-04-29T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65498","published_at":"2026-04-24T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.6551","published_at":"2026-04-26T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65368","published_at":"2026-04-01T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65417","published_at":"2026-04-02T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65444","published_at":"2026-04-04T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65406","published_at":"2026-04-07T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65459","published_at":"2026-04-08T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.6547","published_at":"2026-04-09T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65489","published_at":"2026-04-11T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65476","published_at":"2026-04-12T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65448","published_at":"2026-04-13T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65485","published_at":"2026-04-16T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65496","published_at":"2026-04-18T12:55:00Z"},{"value":"0.00487","scoring_system":"epss","scoring_elements":"0.65481","published_at":"2026-04-21T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2018-20187"},{"reference_url":"https://botan.randombit.net/news.html","reference_id":"","reference_type":"","scores":[],"url":"https://botan.randombit.net/news.html"},{"reference_url":"https://botan.randombit.net/security.html","reference_id":"","reference_type":"","scores":[],"url":"https://botan.randombit.net/security.html"},{"reference_url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-20187","reference_id":"","reference_type":"","scores":[],"url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-20187"},{"reference_url":"https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml","reference_id":"","reference_type":"","scores":[{"value":"2.5","scoring_system":"cvssv3","scoring_elements":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N"}],"url":"https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml"},{"reference_url":"https://github.com/crocs-muni/ECTester","reference_id":"","reference_type":"","scores":[],"url":"https://github.com/crocs-muni/ECTester"},{"reference_url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=918732","reference_id":"918732","reference_type":"","scores":[],"url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=918732"},{"reference_url":"https://nvd.nist.gov/vuln/search/results?adv_search=true&isCpeNameSearch=true&query=cpe:2.3:a:botan_project:botan:*:*:*:*:*:*:*:*","reference_id":"cpe:2.3:a:botan_project:botan:*:*:*:*:*:*:*:*","reference_type":"","scores":[],"url":"https://nvd.nist.gov/vuln/search/results?adv_search=true&isCpeNameSearch=true&query=cpe:2.3:a:botan_project:botan:*:*:*:*:*:*:*:*"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2018-20187","reference_id":"CVE-2018-20187","reference_type":"","scores":[{"value":"4.3","scoring_system":"cvssv2","scoring_elements":"AV:N/AC:M/Au:N/C:P/I:N/A:N"},{"value":"5.9","scoring_system":"cvssv3","scoring_elements":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2018-20187"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/993063?format=json","purl":"pkg:apk/alpine/botan@2.9.0-r0?arch=aarch64&distroversion=v3.15&reponame=main","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/botan@2.9.0-r0%3Farch=aarch64&distroversion=v3.15&reponame=main"}],"aliases":["CVE-2018-20187"],"risk_score":2.6,"exploitability":"0.5","weighted_severity":"5.3","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-31pb-3pss-ybg3"}],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/botan@2.9.0-r0%3Farch=aarch64&distroversion=v3.15&reponame=main"}
