  <description>
    <p>
    Thomas Pollet reported a possible integer overflow vulnerability in the
    PNG image handling in the file filter/image-png.c.
    </p>
  </description>
  <impact type="high">
    <p>
    A malicious user might be able to execute arbitrary code with the
    privileges of the user running CUPS (usually lp), or cause a Denial of
    Service by sending a specially crafted PNG image to the print server.
    The vulnerability is exploitable via the network if CUPS is sharing
    printers remotely.
    </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 &quot;&gt;=net-print/cups-1.2.12-r8&quot;</code>
  </resolution>
