Samba Heimdal Kerberos


Summary

Samba Team has released security updates that address a vulnerability in all versions of Samba from 4.0.0 include an embedded Heimdal Kerberos. Heimdal has made a security release, which disclosed:

Fix CVE-2017-11103: Orpheus' Lyre KDC-REP service name validation

This is a critical vulnerability.

In _krb5_extract_ticket() the KDC-REP service name must be obtained from 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. See https://www.orpheus-lyre.info/ for more details.

The impact for Samba is particularly strong for cases where the Samba DRS replication service contacts another DC requesting replication of user passwords, as these could then be controlled by the attacker.
