    <p>
    MySQL is a popular multi-threaded, multi-user SQL server.
    </p>

  <description>
    <p>
    mu-b discovered a NULL pointer dereference in item_cmpfunc.cc when
    processing certain types of SQL requests. Sec Consult also discovered
    another NULL pointer dereference when sorting certain types of queries
    on the database metadata.
    </p>
  </description>
  <impact type="normal">
    <p>
    In both cases, a remote attacker could send a specially crafted SQL
    request to the server, possibly resulting in a server crash. Note that
    the attacker needs the ability to execute SELECT queries.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All MySQL users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-db/mysql-5.0.38&quot;</code>
  </resolution>
