{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/35568?format=json","vulnerability_id":"VCID-wu1n-6amw-tfd3","summary":"An issue was discovered in fastecdsa before 2.1.2. When using the NIST P-256 curve in the ECDSA implementation, the point at infinity is mishandled. This means that for an extreme value in k and s^-1, the signature verification fails even if the signature is correct. This behavior is not solely a usability problem. There are some threat models where an attacker can benefit by successfully guessing users for whom signature verification will fail.","aliases":[{"alias":"CVE-2020-12607"},{"alias":"GHSA-56wv-2wr9-3h9r"},{"alias":"PYSEC-2020-42"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/16540?format=json","purl":"pkg:pypi/fastecdsa@2.1.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@2.1.2"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/16507?format=json","purl":"pkg:pypi/fastecdsa@1.0.0b1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.0.0b1"},{"url":"http://public2.vulnerablecode.io/api/packages/16508?format=json","purl":"pkg:pypi/fastecdsa@1.0.1b1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.0.1b1"},{"url":"http://public2.vulnerablecode.io/api/packages/16509?format=json","purl":"pkg:pypi/fastecdsa@1.0.1b2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.0.1b2"},{"url":"http://public2.vulnerablecode.io/api/packages/16510?format=json","purl":"pkg:pypi/fastecdsa@1.0.1b3","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.0.1b3"},{"url":"http://public2.vulnerablecode.io/api/packages/16511?format=json","purl":"pkg:pypi/fastecdsa@1.0.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.0.1"},{"url":"http://public2.vulnerablecode.io/api/packages/16512?format=json","purl":"pkg:pypi/fastecdsa@1.0.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.0.2"},{"url":"http://public2.vulnerablecode.io/api/packages/16513?format=json","purl":"pkg:pypi/fastecdsa@1.0.3","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.0.3"},{"url":"http://public2.vulnerablecode.io/api/packages/16514?format=json","purl":"pkg:pypi/fastecdsa@1.1.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.1.0"},{"url":"http://public2.vulnerablecode.io/api/packages/16515?format=json","purl":"pkg:pypi/fastecdsa@1.1.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.1.1"},{"url":"http://public2.vulnerablecode.io/api/packages/16516?format=json","purl":"pkg:pypi/fastecdsa@1.1.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.1.2"},{"url":"http://public2.vulnerablecode.io/api/packages/16517?format=json","purl":"pkg:pypi/fastecdsa@1.1.3","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.1.3"},{"url":"http://public2.vulnerablecode.io/api/packages/16518?format=json","purl":"pkg:pypi/fastecdsa@1.2.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.2.1"},{"url":"http://public2.vulnerablecode.io/api/packages/16519?format=json","purl":"pkg:pypi/fastecdsa@1.3.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.3.1"},{"url":"http://public2.vulnerablecode.io/api/packages/16520?format=json","purl":"pkg:pypi/fastecdsa@1.3.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-8nfq-s4yw-5yab"},{"vulnerability":"VCID-wu1n-6amw-tfd3"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/fastecdsa@1.3.2"},{"url
