208: is being upgraded from OpenSSH 3.0 to OpenSSH 3.0.2 to fix a few problems:

210: <ul>
211: <li>A security hole that may allow an attacker to partially authenticate
212: if -- and only if -- the administrator has enabled KerberosV.
213: <br>
214: By default, OpenSSH KerberosV support only becomes active after KerberosV
215: has been properly configured.
216: <p>
217: <li>An excessive memory clearing bug (which we believe to be unexploitable)
218: also exists, but since this may cause daemon crashes, we are providing a
219: patch as well.
