Synopsis
========

A vulnerability was found in FluidSynth that could result in remote
code execution.

Background
==========

FluidSynth is a real-time synthesizer based on the Soundfont 2
specifications.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-sound/fluidsynth       < 2.2.0                    >= 2.2.0 

Description
===========

FluidSynth contains a use-after-free in sfloader/fluid_sffile.c which
occurs when parsing Soundfile 2 files.

Impact
======

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.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All FluidSynth users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-sound/fluidsynth-2.2.0"
