  <description>
    <p>Multiple vulnerabilities have been discovered in libTIFF. Please review
      the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted TIFF
      file with an application making use of libTIFF, possibly resulting in
      execution of arbitrary code with the privileges of the user running the
      application or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All libTIFF 4.* users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-libs/tiff-4.0.3-r6"
    </code>
    
    <p>All libTIFF 3.* users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-libs/tiff-3.9.7-r1:3"
    </code>
    
    <p>Packages which depend on this library may need to be recompiled. Tools
      such as revdep-rebuild may assist in identifying these packages.
