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.
