{"id":"ALPINE-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","modified":"2026-08-27T22:18:01.864448981Z","published":"2022-11-01T18:15:11.047Z","upstream":["CVE-2022-3786"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2022-3786"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.12.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.12.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.12.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.12.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.12.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.12.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.12.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"nodejs","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/nodejs?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.12.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.0.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.0.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.0.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.0.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.0.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.0.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-3786.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.0.7-r0"}]}],"eco
