    <p>
    Victor Stinner discovered a heap-based buffer overflow in the function
    Get_VMetrics() in src/truetype/ttgload.c when processing TTF files with
    a negative n_points attribute.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted TTF
    file, possibly resulting in the execution of arbitrary code with the
    privileges of the user running FreeType.
    </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-2.3.4-r2"</code>
