    <p>
    Frank Benkstein discovered a possible NULL pointer dereference in
    apps/silcd/command.c if a new channel is created without specifying a
    valid hmac or cipher algorithm name.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could cause the server to crash, resulting in a
    Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All SILC Server users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-im/silc-server-1.0.2-r1&quot;</code>
