DISPUTED The reply function in ftpd.c in the gssftp ftpd in MIT
Kerberos 5 (krb5) does not initialize the length variable when auth_type
has a certain value, which has unknown impact and remote authenticated
attack vectors. NOTE: the original disclosure misidentifies the conditions
under which the uninitialized variable is used. NOTE: the vendor disputes
this issue, stating " The ‘length’ variable is only uninitialized if
‘auth_type’ is neither the ‘KERBEROS_V4’ nor ‘GSSAPI’; this condition
cannot occur in the unmodified source code."
