{"id":"CVE-2022-3786","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.\n\n","aliases":["BIT-node-2022-3786","BIT-node-min-2022-3786","GHSA-h8jm-2x53-xhp5","RUSTSEC-2022-0065"],"modified":"2026-04-10T04:49:56.607718Z","published":"2022-11-01T18:15:11.047Z","related":["ALSA-2022:7288","CGA-mchx-2gcj-cmv7","SUSE-SU-2022:3843-1","SUSE-SU-2022:4586-1","openSUSE-SU-2024:12469-1","openSUSE-SU-2024:12475-1","openSUSE-SU-2024:12479-1","openSUSE-SU-2024:12480-1","openSUSE-SU-2025:14739-1","openSUSE-SU-2025:14740-1"],"references":[{"type":"WEB","url":"https://www.kb.cert.org/vuls/id/794340"},{"type":"ADVISORY","url":"https://www.openssl.org/news/secadv/20221101.txt"},{"type":"ADVISORY","url":"https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00789.html"},{"type":"FIX","url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=c42165b5706e42f67ef8ef4c351a9a4c5d21639a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nodejs/node","events":[{"introduced":"49a77a5a996a49e8cb728eed42e55a7c1a9eef6e"},{"fixed":"8c1dd95f3cc5d91acb9ce8994b3ac45ab927178f"},{"introduced":"0"},{"last_affected":"a4bcc81994c99dbc04089e3ed8d1f5a30a4dc716"},{"introduced":"0"},{"last_affected":"cc993fb2760d01457955f5b9ff787d559ed1c34e"}],"database_specific":{"versions":[{"introduced":"18.0.0"},{"fixed":"18.11.0"},{"introduced":"0"},{"last_affected":"18.12.0"},{"introduced":"0"},{"last_affected":"19.0.0"}]}},{"type":"GIT","repo":"https://github.com/openssl/openssl","events":[{"introduced":"89cd17a031e022211684eb7eb41190cf1910f9fa"},{"fixed":"19cc035b6c6f2283573d29c7ea7f7d675cf750ce"}],"database_specific":{"versions":[{"introduced":"3.0.0"},{"fixed":"3.0.7"}]}}],"versions":["openssl-3.0.0","openssl-3.0.1","openssl-3.0.2","openssl-3.0.3","openssl-3.0.4","openssl-3.0.5","openssl-3.0.6","v0.0.1","v0.0.2","v0.0.3","v0.0.4","v0.0.6","v0.1.0","v0.1.1","v0.1.10","v0.1.100","v0.1.101","v0.1.102","v0.1.103","v0.1.104","v0.1.11","v0.1.12","v0.1.13","v0.1.14","v0.1.15","v0.1.16","v0.1.17","v0.1.18","v0.1.19","v0.1.2","v0.1.20","v0.1.21","v0.1.22","v0.1.23","v0.1.24","v0.1.25","v0.1.26","v0.1.27","v0.1.28","v0.1.29","v0.1.3","v0.1.30","v0.1.31","v0.1.32","v0.1.33","v0.1.4","v0.1.5","v0.1.6","v0.1.7","v0.1.8","v0.1.9","v0.1.92","v0.1.93","v0.1.94","v0.1.95","v0.1.96","v0.1.97","v0.1.98","v0.1.99","v0.2.0","v0.3.0","v0.3.1","v0.3.2","v0.3.4","v0.3.5","v0.3.6","v0.3.7","v0.3.8","v0.4.0","v0.5.0","v0.5.1","v0.5.10","v0.5.2","v0.5.3","v0.5.4","v0.5.5","v0.5.5-rc1","v0.5.6","v0.5.7","v0.5.8","v0.5.9","v0.6.0","v0.6.1","v0.7.0","v0.7.2","v0.7.3","v1.0.1","v1.0.1-release","v1.0.2","v1.0.2-release","v1.0.3","v1.0.4","v1.1.0","v1.2.0","v1.3.0","v1.4.1","v1.4.2","v1.4.3","v1.5.0","v1.5.1","v1.6.0","v1.6.1","v1.6.2","v1.6.3","v1.6.4","v1.7.0","v1.7.1","v18.0.0","v18.1.0","v18.10.0","v18.11.0","v18.12.0","v18.2.0","v18.3.0","v18.4.0","v18.5.0","v18.6.0","v18.7.0","v18.8.0","v18.9.0","v18.9.1","v19.0.0","v2.0.0","v2.0.1","v2.0.2","v2.1.0","v2.2.0","v2.2.1","v2.3.0","v2.3.1","v2.3.2","v2.3.3","v2.3.4","v2.4.0","v2.5.0","v3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-3786.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"36"}]},{"events":[{"introduced":"0"},{"last_affected":"37"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
