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.

12 Aug 2002 — Kerberos 5 su (k5su) in FreeBSD 4.4 and earlier relies on the getlogin system call to determine if the user running k5su is root, which could allow a root-initiated process to regain its privileges after it has dropped them. Kerberos 5 su (k5su) en FreeBSD 4.4 y anteriores se basa en la llamada al sistema getlogin para determinar si el usuario que esta ejecutando k5su es root, lo cual podría permitir a procesos sin privilegios, la obtención de permisos si ese proceso tiene un getlogin como root. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-02:07.k5su.asc •
