Note that this occurs after\ncertificate chain signature verification and requires either a CA to\nhave signed a malicious certificate or for an application to continue\ncertificate verification despite failure to construct a path to a trusted\nissuer. An attacker can craft a malicious email address in a certificate\nto overflow an arbitrary number of bytes containing the `.` character\n(decimal 46) on the stack. This buffer overflow could result in a crash\n(causing a denial of service).\n\nIn a TLS client, this can be triggered by connecting to a malicious\nserver. In a TLS server, this can be triggered if the server requests\nclient authentication and a malicious client connects.\n","affected":[{"package":{"name":"openssl-src","ecosystem":"crates.io","purl":"pkg:cargo/openssl-src"},"ranges":[{"type":"SEMVER","events":[{"introduced":"300.0.0"},{"fixed":"300.0.11"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/11/GHSA-h8jm-2x53-xhp5/GHSA-h8jm-2x53-xhp5.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-3786"},{"type":"WEB","url":"https://github.com/rustsec/advisory-db/pull/1452"},{"type":"WEB","url":"https://github.com/alexcrichton/openssl-src-rs/commit/4a31c14f31e1a08c18893a37e304dd1dd4b7daa3"},{"type":"WEB","url":"https://github.com/openssl/openssl/commit/fe3b639dc19b325846f4f6801f2f4604f56e3de3"},{"type":"WEB","url":"https://www.openssl.org/news/secadv/20221101.txt"},{"type":"WEB","url":"https://www.kb.cert.org/vuls/id/794340"},{"type":"WEB","url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-openssl-W9sdCc2a"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20221102-0001"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202211-01"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2022-0065.html"},{"type":"WEB","url":"https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2022-0023"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/DWP23EZYOBDJQP7HP4YU7W2ABU2YDITS"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/63YRPWPUSX3MBHNPIEJZDKQT6YA7UF6S"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DWP23EZYOBDJQP7HP4YU7W2ABU2YDITS"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/63YRPWPUSX3MBHNPIEJZDKQT6YA7UF6S"},{"type":"PACKAGE","url":"https://github.com/alexcrichton/openssl-src-rs"},{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=c42165b5706e42f67ef8ef4c351a9a4c5d21639a"},{"type":"WEB","url":"https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=c42165b5706e42f67ef8ef4c351a9a4c5d21639a"},{"type":"WEB","url":"http://packetstormsecurity.com/files/169687/OpenSSL-Security-Advisory-20221101.html"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/01/15"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/01/16"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/01/17"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/01/18"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/01/19"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/01/20"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/01/21"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/01/24"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/1"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/10"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/11"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/12"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/13"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/14"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/15"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/2"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/3"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/5"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/6"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/7"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/02/9"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/03/1"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/03/10"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/03/11"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/03/2"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/03/3"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/03/5"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/03/6"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/03/7"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2022/11/03/9"}],"database_specific":{"cwe_ids":["CWE-120"],"github_reviewed":true,"github_reviewed_at":"2022-11-01T17:45:21Z","nvd_published_at":"2022-11-01T18:15:00Z","severity":"HIGH"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
