{"id":"CVE-2017-15088","details":"plugins/preauth/pkinit/pkinit_crypto_openssl.c in MIT Kerberos 5 (aka krb5) through 1.15.2 mishandles Distinguished Name (DN) fields, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) in situations involving untrusted X.509 data, related to the get_matching_data and X509_NAME_oneline_ex functions. NOTE: this has security relevance only in use cases outside of the MIT Kerberos distribution, e.g., the use of get_matching_data in KDC certauth plugin code that is specific to Red Hat.","modified":"2026-05-18T09:05:20.735516Z","published":"2017-11-23T17:29:00.353Z","related":["SUSE-SU-2017:2948-1"],"references":[{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/101594"},{"type":"REPORT","url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=871698"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1504045"},{"type":"FIX","url":"https://github.com/krb5/krb5/commit/fbb687db1088ddd894d975996e5f6a4252b9a2b4"},{"type":"FIX","url":"https://github.com/krb5/krb5/pull/707"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/krb5/krb5","events":[{"introduced":"0"},{"last_affected":"d3cb9e2fbc6a5c7ff67de46473467be127c2df76"}],"database_specific":{"cpe":"cpe:2.3:a:mit:kerberos_5:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"1.15.2"}],"source":"CPE_FIELD"}}],"versions":["krb5-1.15.2-final","krb5-1.15.1-final","krb5-1.15-final","krb5-1.15-beta2","krb5-1.15-beta1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2017-15088.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
