  <description>
    <p>
    Miloslav Trmac from Red Hat discovered a buffer overflow in the
    "readline()" function of texindex.c. The "readline()" function is
    called by the texi2dvi and texindex commands.
    </p>
  </description>
  <impact type="normal">
    <p>
    By enticing a user to open a specially crafted Texinfo file, an
    attacker could execute arbitrary code with the rights of the user
    running Texinfo.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Texinfo users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=sys-apps/texinfo-4.8-r5&quot;</code>
  </resolution>
