In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in \u0027enc_part\u0027 instead of the unencrypted version stored in \u0027ticket\u0027. Use of the unencrypted version provides an opportunity for successful server impersonation and other attacks.
