  <title>lighttpd: Script source disclosure</title>
  <synopsis>
    An attacker can trick lighttpd into revealing the source of scripts that
    should be executed as CGI or FastCGI applications.

  <affected>
    <package name="www-servers/lighttpd" auto="yes" arch="*">
      <unaffected range="ge">1.3.10-r1</unaffected>

  <background>
    <p>
    lighttpd is a small-footprint, fast, compliant and very flexible
    web-server which is optimized for high-performance environments.
    </p>
  </background>
  <description>
    <p>
    lighttpd uses file extensions to determine which elements are programs
    that should be executed and which are static pages that should be sent
    as-is. By appending %00 to the filename, you can evade the extension
    detection mechanism while still accessing the file.
    </p>
  </description>
  <impact type="low">
    <p>
    A remote attacker could send specific queries and access the source of
    scripts that should have been executed as CGI or FastCGI applications.
    </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 "&gt;=www-servers/lighttpd-1.3.10-r1"</code>
  </resolution>
