In versions prior to 1.12.0 a number of vulnerabilities have been found in cosign verify-blob, where Cosign would successfully verify an artifact when verification should have failed. First a cosign bundle can be crafted to successfully verify a blob even if the embedded rekorBundle does not reference the given signature. Second, when providing identity flags, the email and issuer of a certificate is not checked when verifying a Rekor bundle, and the GitHub Actions identity is never checked. Third, providing an invalid Rekor bundle without the experimental flag results in a successful verification. And fourth an invalid transparency log entry will result in immediate success for verification. Details and examples of these issues can be seen in the GHSA-8gw7-4j42-w388 advisory linked. Users are advised to upgrade to 1.12.0. There are no known workarounds for these issues.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2022-09-14 20:15:00","updated_at":"2022-09-19 18:11:00"},"problem_types":["CWE-347"],"metrics":[],"references":[{"url":"https://github.com/sigstore/cosign/security/advisories/GHSA-8gw7-4j42-w388","name":"https://github.com/sigstore/cosign/security/advisories/GHSA-8gw7-4j42-w388","refsource":"CONFIRM","tags":[],"title":"Vulnerabilities with blob verification · Advisory · sigstore/cosign · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/sigstore/cosign/commit/80b79ed8b4d28ccbce3d279fd273606b5cddcc25","name":"https://github.com/sigstore/cosign/commit/80b79ed8b4d28ccbce3d279fd273606b5cddcc25","refsource":"MISC","tags":[],"title":"Merge pull request from GHSA-8gw7-4j42-w388 · sigstore/cosign@80b79ed · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-36056","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36056","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"36056","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"sigstore","cpe5":"cosign","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[{"cve":"CVE-2022-36056","qid":"502840","title":"Alpine Linux Security Update for cosign"},{"cve":"CVE-2022-36056","qid":"752645","title":"SUSE Enterprise Linux Security Update for cosign (SUSE-SU-2022:3486-1)"}]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2022-36056","STATE":"PUBLIC","TITLE":" Vulnerabilities with blob verification in sigstore cosign"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"cosign","version":{"version_data":[{"version_value":"< 1.12.0"}]}}]},"vendor_name":"sigstore"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"Cosign is a project under the sigstore organization which aims to make signatures invisible infrastructure.
