- Mitigation guidance
- Do not enable the FluidSynth TCP server: do not pass -s, and do not call new_fluid_server(). Do not feed untrusted input to the FluidSynth shell. Applications that only use the synthesizer API are not exposed to this flaw. Where the shell or TCP server is required, upgrade to FluidSynth 2.5.6 or later.
