13 Jul 2017 — 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 Heimd... • http://www.debian.org/security/2017/dsa-3912 • CWE-345: Insufficient Verification of Data Authenticity •

12 May 2004 — k5admind (kadmind) for Heimdal allows remote attackers to execute arbitrary code via a Kerberos 4 compatibility administration request whose framing length is less than 2, which leads to a heap-based buffer overflow. k5admind (kadmind) de Heimdal permite a atacantes remotos ejecutar código arbitrario mediante una petición de administración de Kerberos 4 con longitud de marco menor de 2, lo que conduce a un desbordameinte de búfer basado en el montón. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:09.kadmind.asc • CWE-131: Incorrect Calculation of Buffer Size •
