    arbitrary code.

    <p>
    KDE is a feature-rich graphical desktop environment for Linux and
    Unix-like Operating Systems. kfax (part of kdegraphics) is the KDE fax
    file viewer.

  <description>
    <p>
    Than Ngo discovered that kfax contains a private copy of the TIFF
    library and is therefore subject to several known vulnerabilities (see
    References).
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to view a carefully-crafted TIFF
    image file with kfax, which would potentially lead to execution of
    arbitrary code with the rights of the user running kfax.
    </p>
  </impact>
  <workaround>
    <p>
    The KDE Team recommends to remove the kfax binary as well as the
    kfaxpart.la KPart:
    </p>
    <code>
    rm /usr/kde/3.*/lib/kde3/kfaxpart.la
    rm /usr/kde/3.*/bin/kfax</code>
    <p>
    Note: This will render the kfax functionality useless, if kfax
    functionality is needed you should upgrade to the KDE 3.3.2 which is
    not stable at the time of this writing.
    </p>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All kfax users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=kde-base/kdegraphics-3.3.2&quot;</code>
  </resolution>
