  <impact type="normal">
    <p>
    A local attacker could possibly execute arbitrary code or crash the
    Xserver by enticing a user to load a specially crafted PCF font file.
    </p>
  </impact>
  <workaround>
    <p>
    Do not use untrusted PCF Font files.
    </p>
  </workaround>
  <resolution>
    <p>
    All libXfont users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=x11-libs/libXfont-1.2.0-r1&quot;</code>
