    CVE-2017-11103: Orpheus' Lyre KDC-REP service name validation
    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 unecrypted version provides an
    opportunity for successful server impersonation and other attacks.
    Identified by Jeffrey Altman, Viktor Duchovni and Nico Williams.
