{"id":"CVE-2023-46234","summary":"browserify-sign vulnerable via an upper bound check issue in `dsaVerify` that leads to a signature forgery attack","details":"browserify-sign is a package to duplicate the functionality of node's crypto public key functions, much of this is based on Fedor Indutny's work on indutny/tls.js. An upper bound check issue in `dsaVerify` function allows an attacker to construct signatures that can be successfully verified by any public key, thus leading to a signature forgery attack. All places in this project that involve DSA verification of user-input signatures will be affected by this vulnerability. This issue has been patched in version 4.2.2.","aliases":["GHSA-x9w5-v3q2-3rhw"],"modified":"2026-04-16T04:34:41.205089341Z","published":"2023-10-26T14:31:35.895Z","related":["openSUSE-SU-2025:14663-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/46xxx/CVE-2023-46234.json","cwe_ids":["CWE-347"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/10/msg00040.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3HUE6ZR5SL73KHL7XUPAOEL6SB7HUDT2/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/6PVVPNSAGSDS63HQ74PJ7MZ3MU5IYNVZ/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/46xxx/CVE-2023-46234.json"},{"type":"ADVISORY","url":"https://github.com/browserify/browserify-sign/security/advisories/GHSA-x9w5-v3q2-3rhw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-46234"},{"type":"ADVISORY","url":"https://www.debian.org/security/2023/dsa-5539"},{"type":"FIX","url":"https://github.com/browserify/browserify-sign/commit/85994cd6348b50f2fd1b73c54e20881416f44a30"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/browserify/browserify-sign","events":[{"introduced":"36e5387dd0a99ea52f40c9fc142c9e00274aac3a"},{"fixed":"85994cd6348b50f2fd1b73c54e20881416f44a30"}]}],"versions":["v2.6.0","v2.6.1","v2.7.0","v2.7.1","v2.7.2","v2.7.3","v2.7.4","v2.7.5","v3.0.0","v3.0.1","v3.0.2","v3.0.3","v3.0.8","v4.0.0","v4.0.1","v4.0.2","v4.0.3","v4.0.4","v4.1.0","v4.2.0","v4.2.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-46234.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
