{"id":"ALPINE-CVE-2017-11103","details":"Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in 'enc_part' instead of the unencrypted version stored in 'ticket'. Use of the unencrypted version provides an opportunity for successful server impersonation and other attacks. NOTE: this CVE is only for Heimdal and other products that embed Heimdal code; it does not apply to other instances in which this part of the Kerberos 5 protocol specification is violated.","modified":"2026-07-06T00:30:09.977735971Z","published":"2017-07-13T13:29:00.173Z","upstream":["CVE-2017-11103"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2017-11103"}],"affected":[{"package":{"name":"heimdal","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/heimdal?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2017-11103.json"}},{"package":{"name":"heimdal","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine
