Echo: fluidsynth: security update to 2.4.4+dfsg-1+deb13u2+e1

high Tenable Cloud Security Plugin ID 461501

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.2.4 until 2.5.6,
configuring synth.midi-channels above 16 allows the MIDI player to index
_fluid_player_t::channel_isplaying outside its fixed-size heap allocation while tracking active channels.
The resulting out-of-bounds reads and writes invoke undefined behavior and may compromise confidentiality,
integrity, or availability. No crafted MIDI file is required because the unsafe condition is created by
the channel-count configuration itself. Keeping synth.midi-channels at its default value of 16 avoids the
vulnerable path. This issue is fixed in version 2.5.6. (CVE-2026-61714)

Solution

Update the fluidsynth library and its related packages to version 2.4.4+dfsg-1+deb13u2+e1 or later.
