{"id":"GHSA-qwqc-28w3-fww6","summary":"Message Signature Bypass in openpgp","details":"Versions of `openpgp` prior to 4.2.0 are vulnerable to Message Signature Bypass. The package fails to verify that a message signature is of type `text`. This allows an attacker to to construct a message with a signature type that only verifies subpackets without additional input (such as `standalone` or `timestamp`). For example, an attacker that captures a `standalone` signature packet from a victim can construct arbitrary signed messages that would be verified correctly.\n\n\n## Recommendation\n\nUpgrade to version 4.2.0 or later.\nIf you are upgrading from a version \u003c4.0.0 it is highly recommended to read the `High-Level API Changes` section of the `openpgp` 4.0.0 release: https://github.com/openpgpjs/openpgpjs/releases/tag/v4.0.0","aliases":["CVE-2019-9153"],"modified":"2023-11-08T04:01:46.612755Z","published":"2019-08-23T21:42:20Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2019-08-23T21:40:54Z","nvd_published_at":null,"cwe_ids":["CWE-347"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-9153"},{"type":"WEB","url":"https://github.com/openpgpjs/openpgpjs/pull/797/commits/327d3e5392a6f59a4270569d200c7f7a2bfc4cbc"},{"type":"WEB","url":"https://github.com/openpgpjs/openpgpjs/pull/816"},{"type":"WEB","url":"https://github.com/openpgpjs/openpgpjs/releases/tag/v4.2.0"},{"type":"WEB","url":"https://sec-consult.com/en/blog/advisories/multiple-vulnerabilities-in-openpgp-js"},{"type":"WEB","url":"https://snyk.io/vuln/SNYK-JS-OPENPGP-460248"},{"type":"WEB","url":"https://www.bsi.bund.de/SharedDocs/Downloads/EN/BSI/Publications/Studies/Mailvelope_Extensions/Mailvelope_Extensions_pdf.html#download=1"},{"type":"WEB","url":"https://www.npmjs.com/advisories/1160"},{"type":"WEB","url":"http://packetstormsecurity.com/files/154191/OpenPGP.js-4.2.0-Signature-Bypass-Invalid-Curve-Attack.html"}],"affected":[{"package":{"name":"openpgp","ecosystem":"npm","purl":"pkg:npm/openpgp"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.2.0"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 4.1.2","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2019/08/GHSA-qwqc-28w3-fww6/GHSA-qwqc-28w3-fww6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
