Summary

fluidsynth security update

Details

FluidSynth is a free software synthesizer. Its currently based on the SoundFont 2 specifications and supports real time MIDI effect controls. It can be used as a shared library for embedding in other applications, can play MIDI files and has a command line shell. Many other applications use FluidSynth for audio synthesis.

Security Fix(es):

A heap-based buffer overrun was discovered in fluidsynth's command handler. Sending a pitch_bend_range command to the handler with an out-of-bounds channel argument will attempt to write the provided value argument into heap memory. If the command handler is exposed via fluidsynth's TCP server (i.e. created via new_fluid_server() or via fluidsynth -s) an attacker may manipulate heap memory, causing denial of service or remote code execution.(CVE-2026-58264)
