    <package name="media-sound/fluidsynth" auto="yes" arch="*">

  <background>
    <p>FluidSynth is a real-time synthesizer based on the Soundfont 2
      specifications.
    </p>
  </background>
  <description>
    <p>FluidSynth contains a use-after-free in sfloader/fluid_sffile.c which
      occurs when parsing Soundfile 2 files.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted
      Soundfont 2 file using FluidSynth, possibly resulting in execution of
      arbitrary code with the privileges of the process or a Denial of Service
      condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All FluidSynth users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-sound/fluidsynth-2.2.0"
    </code>
