204: is being upgraded from OpenSSH 3.0 to OpenSSH 3.0.2 to fix a few problems:
205: <p>
206: <ul>
207: <li>A security hole that may allow an attacker to partially authenticate
208: if -- and only if -- the administrator has enabled KerberosV.
209: <br>
210: By default, OpenSSH KerberosV support only becomes active after KerberosV
211: has been properly configured.
212: <p>
213: <li>An excessive memory clearing bug (which we believe to be unexploitable)
214: also exists, but since this may cause daemon crashes, we are providing a
215: patch as well.
216: <p>
