  <title>lighttpd: Multiple vulnerabilities</title>
  <synopsis>

    a Denial of Service.

    <p>
    lighttpd is a lightweight high-performance web server.

    <p>
    Julien Cayzax discovered that an insecure default setting exists in
    mod_userdir in lighttpd. When userdir.path is not set the default value
    used is $HOME. It should be noted that the "nobody" user's $HOME is "/"
    (CVE-2008-1270). An error also exists in the SSL connection code which
    can be triggered when a user prematurely terminates his connection
    (CVE-2008-1531).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit the first vulnerability to read
    arbitrary files. The second vulnerability can be exploited by a remote
    attacker to cause a Denial of Service by terminating a victim's SSL
    connection.
    </p>
  </impact>
  <workaround>
    <p>
    As a workaround for CVE-2008-1270 you can set userdir.path to a
    sensible value, e.g. <i>"public_html"</i>.
    </p>
  </workaround>
  <resolution>
    <p>
    All lighttpd users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=www-servers/lighttpd-1.4.19-r2"</code>
  </resolution>
