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

219: <li>Various other non-critical fixes.
