{"id":"ALPINE-CVE-2018-9127","details":"Botan 2.2.0 - 2.4.0 (fixed in 2.5.0) improperly handled wildcard certificates and could accept certain certificates as valid for hostnames when, under RFC 6125 rules, they should not match. This only affects certificates issued to the same domain as the host, so to impersonate a host one must already have a wildcard certificate matching other hosts in the same domain. For example, b*.example.com would match some hostnames that do not begin with a 'b' character.","modified":"2026-07-08T04:31:18.882792605Z","published":"2018-04-02T17:29:00.387Z","upstream":["CVE-2018-9127"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2018-9127"}],"affected":[{"package":{"name":"botan","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}},{"package":{"name":"botan","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/botan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.2.0"},{"fixed":"2.5.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2018-9127.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
