    <package name="x11-libs/qt-gui" auto="yes" arch="*">
      <unaffected range="ge">4.7.4-r1</unaffected>

  <description>
    <p>An error in qtiffhandler.cpp could cause a buffer overflow.</p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted TIFF
      image with an application linked against QtGui, possibly resulting in
      execution of arbitrary code with the privileges of the process or a
      Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All QtGui users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=x11-libs/qt-gui-4.7.4-r1"
    </code>
    
    <p>Packages which depend on this library may need to be recompiled. Tools
      such as revdep-rebuild may assist in identifying some of these packages.
