| 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"
