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