    Multiple integer overflows have been reported in the XGetPixel()
    function of the X.Org X11 library.
    </p>
  </description>
  <impact type="high">
    <p>
    By enticing a user to open a specially crafted image, an attacker could
    cause a Denial of Service or an integer overflow, potentially resulting
    in the execution of arbitrary code with root privileges.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All X.Org X11 library users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=x11-libs/libX11-1.0.3-r2"</code>
