{"id":"BIT-node-2022-3786","summary":"X.509 Email Address Variable Length Buffer Overflow","details":"A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address in a certificate to overflow an arbitrary number of bytes containing the `.' character (decimal 46) on the stack. This buffer overflow could result in a crash (causing a denial of service). In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects.","aliases":["BIT-node-min-2022-3786","CVE-2022-3786","GHSA-h8jm-2x53-xhp5","RUSTSEC-2022-0065"],"modified":"2025-11-06T13:25:46.476Z","published":"2024-03-06T11:02:40.764Z","database_specific":{"cpes":["cpe:2.3:a:nodejs:node.js:*:*:*:*:-:*:*:*","cpe:2.3:a:nodejs:node.js:18.12.0:*:*:*:lts:*:*:*","cpe:2.3:a:nodejs:node.js:19.0.0:*:*:*:-:*:*:*","cpe:2.3:a:nodejs:node.js:*:*:*:*:lts:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=c42165b5706e42f67ef8ef4c351a9a4c5d21639a"},{"type":"WEB","url":"https://www.openssl.org/news/secadv/20221101.txt"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-3786"},{"type":"WEB","url":"https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00789.html"},{"type":"WEB","url":"https://www.kb.cert.org/vuls/id/794340"}],"affected":[{"package":{"name":"node","ecosystem":"Bitnami","purl":"pkg:bitnami/node"},"ranges":[{"type":"SEMVER","events":[{"introduced":"18.0.0"},{"fixed":"18.11.0"},{"introduced":"18.12.0"},{"fixed":"18.12.1"},{"introduced":"19.0.0"},{"fixed":"19.0.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/node/BIT-node-2022-3786.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.7.3"}
