** 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."
