Problem Description:

 The new OpenSSH 3.0.2 fixes a vulnerability in the UseLogin option.
 By default, Mandrake Linux does not enable UseLogin, but if the

 variables to the login process.  This update also fixes a security
 hole in the KerberosV support that is present in versions 2.9.9 and
 3.0.0.
