  <description>
    <p>
    Tielei Wang reported multiple integer overflow vulnerabilities in the
    tiff_instantiate(), png_instantiate() and jpeg_instantiate() functions
    in glyphs-eimage.c, all possibly leading to heap-based buffer
    overflows.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted TIFF,
    JPEG or PNG file using XEmacs, possibly resulting in the remote
    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 XEmacs users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-editors/xemacs-21.4.22-r1"</code>
    <p>
    NOTE: This is a legacy GLSA. Updates for all affected architectures are
    available since July 26, 2009. It is likely that your system is already
    no longer affected by this issue.
