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

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

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

Impact

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
