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.\r\n\r\nSecurity Fix(es):\n\nA 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)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"fluidsynth","purl":"pkg:rpm/openEuler/fluidsynth&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3.4-3.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["fluidsynth-2.3.4-3.oe2403sp1.aarch64.rpm","fluidsynth-debuginfo-2.3.4-3.oe2403sp1.aarch64.rpm","fluidsynth-debugsource-2.3.4-3.oe2403sp1.aarch64.rpm","fluidsynth-devel-2.3.4-3.oe2403sp1.aarch64.rpm","fluidsynth-help-2.3.4-3.oe2403sp1.aarch64.rpm"],"src":["fluidsynth-2.3.4-3.oe2403sp1.src.rpm"],"x86_64":["fluidsynth-2.3.4-3.oe2403sp1.x86_64.rpm","fluidsynth-debuginfo-2.3.4-3.oe2403sp1.x86_64.rpm","fluidsynth-debugsource-2.3.4-3.oe2403sp1.x86_64.rpm","fluidsynth-devel-2.3.4-3.oe2403sp1.x86_64.rpm","fluidsynth-help-2.3.4-3.oe2403sp1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2960"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58264"}],"database_specific":{"severity":"Critical"}}
