    <p>
    Roee Hay reported a stack-based buffer overflow in the push_subg()
    function in parser.y when processing a DOT file with a large number of
    Agraph_t elements.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user or automated system to open a
    specially crafted DOT file in an application using Graphviz, possibly
    leading to the execution of arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Graphviz users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-gfx/graphviz-2.20.3&quot;</code>
  </resolution>
