  <title>CUPS: Multiple vulnerabilities</title>
  <synopsis>
    Multiple errors in CUPS might allow for the remote execution of arbitrary
    code or DNS rebinding attacks.

  <background>
    <p>
    CUPS, the Common Unix Printing System, is a full-featured print server.
    </p>
  </background>
  <description>
    <p>
    The following issues were reported in CUPS:
    </p>
    <ul>
    <li>iDefense
    reported an integer overflow in the _cupsImageReadTIFF() function in
    the "imagetops" filter, leading to a heap-based buffer overflow
    (CVE-2009-0163).</li>
    <li>Aaron Siegel of Apple Product Security
    reported that the CUPS web interface does not verify the content of the
    "Host" HTTP header properly (CVE-2009-0164).</li>
    <li>Braden Thomas and
    Drew Yao of Apple Product Security reported that CUPS is vulnerable to
    CVE-2009-0146, CVE-2009-0147 and CVE-2009-0166, found earlier in xpdf
    and poppler.</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker might send or entice a user to send a specially
    crafted print job to CUPS, possibly resulting in the execution of
    arbitrary code with the privileges of the configured CUPS user -- by
    default this is "lp", or a Denial of Service. Furthermore, the web
    interface could be used to conduct DNS rebinding attacks.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All CUPS users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-print/cups-1.3.10"</code>
  </resolution>
