    <p>
    Robert Jakabosky discovered an infinite loop triggered by a connection
    abort when Lighttpd processes carriage return and line feed sequences.
    Marcus Rueckert discovered a NULL pointer dereference when a server
    running Lighttpd tries to access a file with a mtime of 0.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could upload a specially crafted file to the server
    or send a specially crafted request and then abort the connection,
    possibly resulting in a crash or a Denial of Service by CPU
    consumption.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Lighttpd users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-servers/lighttpd-1.4.14&quot;</code>
  </resolution>
