    <p>
    FreeRADIUS is an open source RADIUS authentication server
    implementation.
    </p>

  <description>
    <p>
    Primoz Bratanic discovered that the sql_escape_func function of
    FreeRADIUS may be vulnerable to a buffer overflow (BID 13541). He also
    discovered that FreeRADIUS fails to sanitize user-input before using it
    in a SQL query, possibly allowing SQL command injection (BID 13540).
    </p>
  </description>
  <impact type="normal">
    <p>
    By supplying carefully crafted input, a malicious user could cause an
    SQL injection or a buffer overflow, possibly leading to the disclosure
    and the modification of sensitive data or Denial of Service by crashing
    the server.
    </p>
  </impact>
  <workaround>
    <p>
    There are no known workarounds at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All FreeRADIUS users should upgrade to the latest available version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-dialup/freeradius-1.0.2-r4"</code>
  </resolution>
