  <background>
    <p>The TIFF library contains encoding and decoding routines for the Tag
      Image File Format. It is called by numerous programs, including GNOME and
      KDE applications, to interpret TIFF images.
    </p>

  <description>
    <p>Multiple vulnerabilities have been discovered in LibTIFF. Please review
      the referenced CVE identifiers for details.
    </p>
    
  </description>
  <impact type="normal">
    <p>A remote attacker, by enticing the user to process a specially crafted
      TIFF file, could possibly execute arbitrary code with the privileges of
      the process, cause a Denial of Service condition, obtain sensitive
      information, or have other unspecified impacts.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All LibTIFF users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-libs/tiff-4.0.8"
    </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.
