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." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "name": "https://support.apple.com/HT208221", "refsource": "CONFIRM", "url": "https://support.apple.com/HT208221" }, { "name": "DSA-3912", "refsource": "DEBIAN", "url": "http://www.debian.org/security/2017/dsa-3912" }, { "name": "https://support.apple.com/HT208144", "refsource": "CONFIRM", "url": "https://support.apple.com/HT208144" }, { "name": "https://www.orpheus-lyre.info/", "refsource": "MISC", "url": "https://www.orpheus-lyre.info/" }, { "name": "FreeBSD-SA-17:05", "refsource": "FREEBSD", "url": "https://www.freebsd.org/security/advisories/FreeBSD-SA-17:05.heimdal.asc" }, { "name": "99551", "refsource": "BID", "url": "http://www.securityfocus.com/bid/99551" }, { "name": "1039427", "refsource": "SECTRACK", "url": "http://www.securitytracker.com/id/1039427" }, { "name": "https://www.samba.org/samba/security/CVE-2017-11103.html", "refsource": "CONFIRM", "url": "https://www.samba.org/samba/security/CVE-2017-11103.html" }, { "name": "1038876", "refsource": "SECTRACK", "url": "http://www.securitytracker.com/id/1038876" }, { "name": "https://support.apple.com/HT208112", "refsource": "CONFIRM", "url": "https://support.apple.com/HT208112" }, { "name": "https://github.com/heimdal/heimdal/releases/tag/heimdal-7.4.0", "refsource": "CONFIRM", "url": "https://github.com/heimdal/heimdal/releases/tag/heimdal-7.4.0" }, { "name": "http://www.h5l.org/advisories.html?show=2017-07-11", "refsource": "CONFIRM", "url": "http://www.h5l.org/advisories.html?show=2017-07-11" } ] } }
