GLSA 202107-34: FluidSynth: Remote code execution

Severity:normal
Title:FluidSynth: Remote code execution
Date:07/15/2021
Bugs: #782700
ID:202107-34

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 Architecture(s)
media-sound/fluidsynth < 2.2.0 >= 2.2.0 All supported architectures

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"
