    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted image
      file using exif or an application linked against libexif, 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 libexif users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-libs/libexif-0.6.21"
    </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.
    </p>
    
    <p>All exif users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
