{"id":"UBUNTU-CVE-2023-46234","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.","modified":"2026-01-30T01:15:18.422703Z","published":"2023-10-26T15:15:00Z","related":["USN-6800-1"],"upstream":["CVE-2023-46234"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-46234"},{"type":"REPORT","url":"https://github.com/browserify/browserify-sign/security/advisories/GHSA-x9w5-v3q2-3rhw"},{"type":"REPORT","url":"https://github.com/browserify/browserify-sign/commit/85994cd6348b50f2fd1b73c54e20881416f44a30"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-46234"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6800-1"}],"affected":[{"package":{"name":"node-browserify-sign","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/node-browserify-sign@4.0.4-2ubuntu0.18.04.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.0.4-2ubuntu0.18.04.1~esm1"}]}],"versions":["4.0.4-1ubuntu1","4.0.4-2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-browserify-sign","binary_version":"4.0.4-2ubuntu0.18.04.1~esm1"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46234.json"}},{"package":{"name":"node-browserify-sign","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/node-browserify-sign@4.0.4-2ubuntu0.20.04.1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.0.4-2ubuntu0.20.04.1"}]}],"versions":["4.0.4-2"],"ecosystem_specific":{"binaries":[{"binary_name":"node-browserify-sign","binary_version":"4.0.4-2ubuntu0.20.04.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46234.json"}},{"package":{"name":"node-browserify-sign","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/node-browserify-sign@4.2.1-2ubuntu0.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.2.1-2ubuntu0.1"}]}],"versions":["4.2.1-1","4.2.1-2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"4.2.1-2ubuntu0.1","binary_name":"node-browserify-sign"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-46234.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
