  <description>
    <p>
    Tavis Ormandy reported multiple integer overflows in the
    cff_charset_compute_cids() function in cff/cffload.c, sfnt/tccmap.c and
    the ft_smooth_render_generic() function in smooth/ftsmooth.c, possibly
    leading to heap or stack-based buffer overflows.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user or automated system to open a
    specially crafted font file, possibly resulting in the execution of
    arbitrary code with the privileges of the user running the application,
    or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All FreeType users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-libs/freetype-2.3.9-r1"</code>
  </resolution>
